The Wizard of Oz is an American Classic - both the book and the movie. It's also a wonderful example of wind uplift. During the frightening tornado, Dorothy's farmhouse is literally lifted up off the ground, like an airplane or kite, and re-deposited directly on top of the Wicked Witch of the West. When air pressure below a roof line is greater than the air pressure above the roof line - common in situations where high winds cause air to move directly into a building as well as across the top of the building - the roof and a well-attached building below can literally take flight. Metal buildings are particularly susceptible to wind uplift because they are lighter than traditional wood-framed buildings and, without careful design attention, they may not be anchored by the proper foundation. KEEP INSURANCE COSTS DOWN: DESIGN TO CURRENT WIND UPLIFT RATING REQUIREMENTS While entire buildings aren't typically lifted as the result of high wind, serious damage can occur as

Strength. Durability. Longevity: all are attributes associated with steel barns. But these attributes are only possible if the building is well-designed from start to finish. Similar to the idea that, "a chain is only as strong as its weakest link," a steel building is only as strong as the weakest foundation, fastener, roof design, name-your-part. Any steel building's overall design is critical to securing it season by season, year by year and decade by decade. SECURING A STEEL BARN BEGINS WITH SOUND SITE SELECTION The design process begins well before you ever break ground; it begins with your site selection. A large part of your building's lifetime security depends on its foundation, and a strong foundation relies on stable ground that is free from standing water or erosive water runoff. Pay close attention to the way water diverts during times of high rain and/or snow melt and try to choose a location that is free of the main, natural water ways. Tips t

High-tech gadgets is a buzz phrase seen over and over again, Purlin Roll Forming Machine from design and manufacturing entities to kitchen and bathroom fixtures. Innovations currently available to construction industry professionals is the stuff futuristic dreams were made of just a a few decades ago. Those who work in this modern era can enjoy a remarkable array of tools, equipment and even clothing - all of which streamline the design and build process, improve communication both in-house and with clients and/or improve worker safety. 5 CONSTRUCTION GADGETS THAT CAN REVOLUTIONIZE THE WAY YOU WORK Construction management software and innovative marketing tools are macro-versions of innovative construction solutions.. Now it's time to focus on the micro-perspective - taking a look at actual equipment that improve the working lives of the people you value most: your employees. Not only will the following tools help employees to work more efficiently, most of them will als

There are several advantages to metal roofs - 40-year warranties, Roof Panel Forming Machine water-shedding properties and energy-efficiency being some of the more publicized examples. A lesser discussed but equally attractive advantage is that a metal roofing system can often be installed right over an existing roof. INSTALLING A METAL ROOF OVER AN EXISTING SHINGLE ROOF The pros: Reduced cost Reduced labor Increased thermal resistance (R-value) of completed roof system Faster completion time Minimizes unnecessary landfill waste A properly installed metal roof lasts for multiple decades The cons: It shouldn't be done if there are more than two layers of existing roofing materials Underlying shingles can experience moisture and other potential wear and tear issues if the metal roof is not installed properly Potential problems with the local building department The cons shouldn't be much of a deterrent if you have done your homework, work with an experienced m

No matter how hard you work to keep your steel frame machine job sites safe, accidents are bound to happen. When they do, a contractor liability insurance policy is designed to protect your company's financial interests so any immediate financial liability - or financial damages as the result of a lawsuit - can be handled expediently and efficiently without posing a significant risk to your business. THE BASICS OF CONTRACTOR LIABILITY INSURANCE Your contractor insurance policy can be activated via several scenarios: Property Damage Claims. These claims are designed to cover the costs of a lawsuit if a building or property owner claims that the work performed by your company was responsible for major property damage, or that activities or work performed by you has rendered the property unusable or uninhabitable. It's important to note that this type of coverage does not typically protect contractors who do remodeling and renovation work, so an umbrella or gap insurance po

Wouldn't it be nice if a company could provide a single, roll forming machine solid figure for the total building cost? The reality is there is absolutely no way to do that because there are too many variables involved with any construction project - from design and change orders to weather delays and materials selection, to name a few. PRE-ENGINEERED METAL BUILDINGS COST LESS IN THE LONG RUN What is certain is that when planned and designed well, and when experienced metal building manufacturers and builders are used, the cost of a metal building is almost surprising. In some cases, the total costs for a pre-engineered building is upwards of 40% less than other types of construction, due to the ease and speed of construction, and that's without taking lifetime costs into consideration. So, while providing an exact figure isn't possible, it is possible to outline factors that make steel buildings affordable in the big picture. PRE-ENGINEERING REDUCES MATERIALS WAST

 LEED certification program is a product of the U.S. Green Building Council and is now an internationally recognized system for ensuring and measuring the sustainability of new building designs. It is setup using a combination of categories and points. A building's design and material selection must gain a set number of points in a range of categories in other to earn the distinction of being LEED certified.  Green roofs benefit builders striving for LEED certification in two ways. Not only are the roofs' energy-efficient and durable characteristics worthy of points, they also help to improve a building's overall performance, which earns additional points. Cool metal roofs can earn points in several categories such as: Sustainable Sites. Gain points in regards to the reduction of urban heat island effect as well as low slope and Solar Reflective Index Requirements (SRI). Water Efficiency. You can use gutters, downspouts and other elements of a rain-water collection

Typically, the effectiveness of insulation versus a cool metal roof isn't an either/or question. Most building codes require some amount of insulation - quantity and R-Value being dictated by the climate where you live. Cool metal roofs, on the other hand, are specifically designed for warm and hot weather climates, where the lion's share of undesirable heat transfer is the result of UV absorption through the roof. Most building experts recommend using a combination of insulation and a reflective metal roofing system in order to optimize energy efficiency and interior comfort while minimizing solar heat gain since insulation and reflective roofs mitigate heat transfer differently. INSULATION HELPS TO REDUCE THREE TYPES OF SOLAR HEAT GAIN Insulation provides a thermal barrier, preventing heat transfer from one space to another. This heat transfer occurs in three ways: Conduction: This occurs when heat moves through a particular material, conducting heat from one source

Metal building contractors are constantly reminded, "water is the enemy," encouraged to choose the right site location, building materials and techniques to avoid long-term moisture exposure. This time of year however, it's important to review the building practices you're implementing from job site to site, making sure rainfall, snow melt and mudslides aren't creating irreversible damage to the property and/or its surrounding environment. Erosion control is nothing to take lightly. In addition to posing a threat to the environment via sediment run-off that pollutes storm drains, nearby streams and other bodies of water, storm water-related erosion poses immediate health and safety concerns to your employees, site occupants and neighbors. Additionally, failure to observe careful and methodical erosion control methods can be costly in terms of litigation from adjacent and/or down-slope property owners, not to mention the fines associated with potential local

When selecting the fasteners for your metal roofing system, you'll have two options: concealed or exposed. As one would expect, the former is hidden from view while the latter is visible in plain sight. There are pros and cons to each, and its important to always match the proper fastener-type with the right metal roofing system. Concealed fastener metal roofs provide a clean and streamlined finish. While a bit more expensive and labor intensive at the outset, they deliver multiple benefits, including: Reduced wear and tear on the fasteners Less distortion of the roof panels Increased leak resistance Improved looks Spend time browsing websites and brochures from metal building manufacturers to pick a few styles you like, then work more closely with a preferred manufacturer to make sure the roof and fastener systems work with your climate and your building codes. BENEFITS OF CONCEALED FASTENER METAL ROOFING The following are expanded benefits of using concealed fastener

Trying to decide whether or not to build traditionally with wood or opt for a more modern, steel building approach? There's no need to choose one over the other. These days, many builders go the hybrid construction route, blending their favorite attributes of wood-framed and trimmed homes with the strength and durability of steel and metal building components. STEEL TRUMPS WOOD IN MANY CASES One of the reasons hybrid construction projects are increasingly desirable is that local building codes are beefing up their efforts to improve occupant and environmental safety. From wind uplift ratings to eco-friendliness - there are several ways that steel and metal trump wood, or vice versa in other cases, and it is a desire to find solutions to particular building challenges that has led architects and builders to seek a more hybridized path. Wind and snow load resistance. Building codes are often based on 100-year weather patterns, and lately those patterns are a changin'. Revie

Fast-growing school populations, the need for quick purlin machine manufacturers in india and economical construction, and tighter building budgets are just a few of the challenges facing the educational sector today. After the Baby Boom large numbers of schools were built to accommodate all the children of those coming back from World War II. As those children graduated, fewer schools were needed and many were closed or are aging. Now, as the children of Boomers and Generations X and Y are swelling the population, new schools are needed again. However, the requirements of an educational facility, from nursery school to university, have changed since that first huge wave of Boomers. Schools must be safer, provide more flexibility and services, and cost less to build yet be built quickly. Concrete, stone, and wood construction is no longer a viable choice. BUILD YOUR EDUCATIONAL FACILITY WITH STEEL Steel is the most advanced durable material in construction today. Steel is the c

As 2015 draws to a close, it's time to take stock and look steel framing systems ahead to the trends that are driving the construction industry into 2016. It's no surprise that sustainability and technology continue to top the list, but others may surprise you. Here's a look at seven trends that will impact construction in 2016. SUSTAINABILITY There's no doubt about it; sustainability continues to be the leading trend for all aspects of construction - from design to actual installation. Prior to the past several years, sustainable features, like solar panels and water-saving plumbing fixtures, were added as retrofits. Now, both developers and building owners recognize that it's more affordable to integrate sustainable features into the design at the outset. Building materials are also assessed for their "green factor," and builders look to green building certification programs like LEED when making their selections. The market share for products s

For stability with flexibility nothing beats roll former manufacturers continuous steel beam construction. Continuous steel beams are created by joining two or more beams rigidly together over multiple support points. This method of construction creates a stiffer and stronger member than a simple supported beam and is ideal for providing brace free spaces and flexible arrangements of columns. If you need a building with open space, particularly near the roof or ceiling, continuous beam is highly recommended. Continuous steel beams allow for large, high door openings for large vehicles or other equipment as well as a floor with efficiently placed columns for forklift traffic. If your design does not include bracing, continuous steel beam can create a building frame strong enough to exclude it. CONTINUOUS STEEL BEAMS: A DEFINITION A continuous steel beam contains two or more beams joined by multiple beam supports. Spans are usually in a straight line and have two or more support

It's never been easier to enjoy the benefits of solar power. roll former Continued technological innovation have made solar panels more affordable than ever before, and many homeowners are taking advantage of lease options, which eliminates their financial and maintenance-related responsibility for the panels while simultaneously slashing their household's energy spending. According to a a study from GTM Research and the Solar Energy Industries Association, 2013's third quarter marked the largest quarter ever for solar or photovoltaic (PV) installations yet. Homeowners appreciate the fact that: In all but a few states, utility companies pay homeowners for excess energy generation by crediting future energy bills. Solar power is a key feature in sustainable homes or developments striving to meet net-zero or Passive House standards. A PV system scores LEED points both directly, and indirectly, depending on the percentage of the building's total energy consumptio
