The most prized types of windows and doors—composed of custom, handcrafted, solid, hot-rolled steel—grace innumerable luxury residential, commercial, cultural, institutional, and historically prominent structures across the United States.
Drywall is often misperceived as a building material that does not demand the skillful manipulation of a traditional construction material. However, anyone who has worked with drywall knows the product is not so cooperative.
Similar to most industrial sectors, regulatory requirements in both pharmaceutical and food manufacturing have become more stringent than ever. In response, the equipment and processes used in these industries have also become more sophisticated.
Specifying and installing doors and hardware has become increasingly complex. Integrated doors have emerged as a popular solution to combat this trend, and make it easier to select and install the correct product for many types of openings.
Warehouse doors can help increase safety by helping protect the integrity of the floor. They are designed to prevent the elements from the entering the facility, and reduce the threat of condensation from creating a slipping/tripping hazard for those on foot or those trying to quickly maneuver forklifts in tight areas. They also serve to reduce impact accidents and injuries by absorbing ‘hits.’ To ensure the right assembly, there are numerous high-pressure and missile-impact tests that demonstrate the strength of the doors—important for facing up to high winds.
Exterior door assemblies not covered by Florida Building Code (FBC) 1715.5.2, “Exterior Windows, Siding, and Patio Glass,” or FBC 17188.8.131.52, “Exterior Door Assemblies,” shall be tested for structural integrity in accordance with Procedure A of ASTM E330, Standard Test Method for Structural Performance of Exterior Windows, Doors, Skylight,s and Curtain Walls by Uniform Static Air Pressure Difference, at a load of 1.5 times the required design pressure load. The load shall be sustained for 10 seconds with no permanent deformation of any main frame or panel member in excess of 0.4 percent of its span after the load is removed. The design pressures, as determined from American Society of Civil Engineers (ASCE) 7, Minimum Design Loads for Buildings and Other Structures, are permitted to be multiplied by 0.6. High-velocity hurricane zones (HVHZ) must comply with Testing Application Standard (TAS) 202. After each specified loading, there must be no glass breakage, permanent damage to fasteners, hardware parts, or any other damage that causes the door to be inoperable.
