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.

Before you Buy

Do you know the company you're doing business with? Is the supplier a member of the Better Business Bureau? Do they have a record of dealing honestly? Can they refer you to satisfied customers? Is the physical address to the company available? Can you visit them at their offices? Are they a real company with a history of quality manufacturing? Are they Active Members of the AISC (American Institute of Steel Construction) Do they post any affiliation with any steel building association? Do you know what you are paying for? Does the steel building contract give line-item prices? Will you receive comprehensive set of erection plans? Are you getting written 30-year paint and 25-year Galvalume Plus® warranties? Does the contract specify 26 gauge panels? Does their roof panels include a "purlin bearing" leg? Does the roof system have an Underwriters Laboratories Class 90 rating? Are you being supplied with premium fasteners with a lifetime red-rust warranty? Will your steel building have a sculptured trim package? Are all the clips welded to primary structural components? Are the framed openings factory located? Does the supplier have the ability to engineer a custom design? Will you receive an 80+ page fully illustrated erection manual? Does the supplier have an in-house customer service department? Does the supplier actually manufacture what they sell? Do they process and produce all their drawings in-house? Do they ask you to sign a contract and pay a deposit before you know the total cost?

General Guidelines

When you decide to buy a Building - Confirm the accuracy of your building codes. It is imperative that your building conforms to the state, local and federal design requirements.

The items described on your contract are what you are buying. Please be sure to carefully review all contract documents before you sign off. If a contract does not describe an item in specific terms, you should not expect the item to be the best product available. And just as important - is what a contract does not say. Specifically if your contract does not indicate that you are getting framed openings and garage doors - then you are NOT going to get framed openings and garage doors.

Do not sign a contract or agree to purchase a building before you have confirmed that your building will satisfy the requirements of your local building official and YOURSELF. Do not allow a salesman to pressure you into a "panic buy." A "panic buy" is when a customer is pressured into making a purchase to "lock-in" a "so-called" special price. Brokers are notorious for telling customers they could lose an opportunity to get the "deal of a lifetime" if they don't commit to the order right away. Beware of people who urge you to sign a contract before you have made your mind up on exactly what you want.

Understand that making changes after the sale will cost you money. Once the design is completed it will cost money to make changes. If an order is in fabrication - and requires modifications due to customer demands - the entire process has to be stopped, pulled off-line and inventoried. Once the inventory of completed items is confirmed, it's back to the drawing board. You will be responsible for extra time required to re-design the project and all other associated expenses.

Install your building components as specified by the drawings. Seldom do manufacturers use the same design practices and therefore your erection drawings and installation documents are the correct description of the building. Please read and follow the drawing descriptions carefully. An erection manual offers important general guidelines and the proper procedures for erecting a steel building safely. You, your erector and all jobsite crew need to understand and utilize OSHA and all other safety guidelines.

Panel Profiles

Roof Panel Profiles - Our standard roof sheeting is the "PBR" panel, which is available in bare Galvalume Plus® as well as a variety of colors. Wall sheeting is available in "R" and "PBR" panel. Depending on the color and your geographic location - PBR panels may not be available for certain colors.

Liner Panels - For liner panels we offer a low-rib 29-gauge panel. Liner panels are an interior covering for the walls of a steel building. Like exterior walls, liner panel consists of 3-foot wide panels that are attached to the framing in the same manner as exterior sheeting. Full-height liners run from floor to roof. Partial-height liners typically attach to the girt at 7'4" and extend a few inches above it. Buildings with liner panels must have a base connection for the bottom of the panel (see base conditions).

Advantages - Liner Panels enhance appearance, providing a finished look for the interior. The biggest advantage is that liners protect the insulation and the outside walls. Because un-reinforced insulation facings tear easily, and even the best-reinforced materials can be damaged, liner panels are the intelligent solution to protect your investment. Although 26-gauge exterior walls can withstand a lot of punishment, a steel liner will protect your building's interior and performs at a lower cost than other wall coverings, which will require their own framing.

Recommended Installation Methods of Insulation

Roof insulation rolls are cut to lengths that will cover the distance from eave to eave, leaving a one-foot overhang on each side of the building.

1) Start at the end of the building and temporarily secure one end of the roll by attaching the insulation to the eave strut with double-faced tape.

2) Pull the insulation across the purlins with the vapor barrier toward the building interior. Double-faced tape attached to the opposite end of the insulation will keep tension on the roof roll while the metal panels are being attached over the insulation.

3) Install the next roll in the same manner, making sure the rolls are stretched tight, aligned properly and closely butted.

4) Fasten tabs using one of the methods described on the following page. Any rips or tears must be covered with matching facing tape to ensure a tight vapor seal.

5) Trim excess insulation flush to prevent it from acting as a wick and moving water into the building.
