Structural Design

We design and manufacture pre-engineered steel buildings, and offer you a number of advantages over conventional construction techniques. Steel buildings are inexpensive and incredibly tough. Our bolt-together design is assembled quickly without any specialized skills. Each rigid frame is comprised of two or more columns supporting a rafter across the width of the building. In most steel buildings, endwall bearing frames support one-half the load of a rigid "main" frame. In most situations, we utilize the more economical "bearing" end frames. Adding an expandable endwall or rigid frame is only a click away. Unlike any of our competitors, we allow you to choose the endwall condition of your building. Depending on design considerations, our endwall rafters and columns may be either hot rolled or cold-formed.

The space between the rigid frames of a steel building is referred to as a "bay."- an 80' long building has been divided into four 20' bays by spacing the frames 20' apart (4 x 20' = 80'). This configuration is described as "four bays at 20." A 100' building could be configured with four bays at 25 (4x 25' = 100')

Endwall bay spacing is usually determined by the building width. You can add one or more framed openings to most buildings. Endwall bay spacing can usually changed to accommodate your needs without changing the price.

Walk Doors

Walk doors can be provided as pre-assembled or knock down (field assembled). Metal Building Depot provides solid doors for both options in the following sizes: 3070, 4070, and 6070. The walk doors are typically keyed alike per project. Because of unknown variables, Metal Building Depot does not offer fire rated doors or doors to fit in masonry.

Features of the pre-assembled doors are as follows:

Foam insulated specifically designed for metal building use. Pre-assembled and self-framing for ease of installation. No framed opening required if Metal Building Depot standard girt spacing is utilized. Doors are finished in a two-coat primer; color selection is white or bronze. Doors are shipped in wood crates for protection. All doors have Grade 2 lever locks as standard. Hinges are ball bearing and powder coated. Insulated jambs. 3070 and 6070 doors are made of 20-gage material, 18 gage is available.

Features of the knock down doors are as follows:

Foam insulated specifically designed for metal building use. The walk door is shipped knocked down for field assembly. Doors are textured 20 gage galvanized prime painted and pre-finished in either white or bronze. Weather stripping and standard entrance lock is included. The walk door package is shipped with polybag and full cardboard carton. All doors have Grade 2 lever locks as standard. Hinges are ball bearing and powder coated.

Metal Building Kit

Purchasing your new metal building kit. You should be cautious when buying a metal building kit. Not every manufacturer uses high quality materials or fabricates to the latest industry standards. You don't want to purchase a building from a manufacturer (or broker) whose building parts were produced in a factory without the benefit of a skilled eye to oversee the process.

A pre-engineered metal building should come with a complete and comprehensive set of blueprints. When a qualified steel building manufacturer puts its seal of approval on your building design you can rest assured of its structural integrity. You can expect detailed documentation about the building's fabrication and its specific code requirements as well.

Before you purchase a metal building kit you should attempt to create a basic plan for its end use and design. Working with a professional steel building company should ensure that all facets of your building are taken into consideration. They can explain the building options and codes in detail so you have the accurate building specifications.

Surface Air Film Coefficient (F)

The amount of heat flow in BTU's per square foot per hour between an exposed surface of a material and the adjacent air. It is the measure of the conductance of heat through the air film that clings to all surfaces.

Constructing a Large Steel Building

Have you considered all of your steel building options? There are many types of standard buildings to choose from, but they are not the only option. Buildings can be finished with a multitude of options and accessories. Your land and location will control some of the parameters of the kind of structure you need. Aside from these factors you can make the choices based on your preferences. Windows, skylights and panel styles can be individually selected to comprise a personal metal building kit.

Pre-engineered metal building plans are just the starting point from which you can select options and accessories. Configuring your building may sound like a small deal, but it determines the type building you will purchase. Not every large steel building is intended to be a large shop. When you work with the manufacturer you can customize a structure with a polished look and feel. Regard your steel metal building as a low cost alternative to traditional construction.
