Accessories & Components
The basic structure of a Mueller steel building is made up of components. Mueller has intense quality control measures that provide consistency and durability in all of our steel products. Our top priority is quality products along with customer satisfaction. That is why all manufacturing for our steel buildings and metal roofing products is done in one of our three Texas manufacturing facilities.
The roof purlins provide a surface to which the roof panels can be attached. Mueller offers you a choice in run-to-length purlin: #1 spec material for engineered structures, and high strength material for weld-together projects. These two options help meet your specific needs while also giving you the luxury of specified lengths. #1 Engineered Structural Shapes with the Mueller Punch Pattern. (Custom punched patterns are available, please contact your Mueller sales representative)

A primary member, usually horizontal, that is subjected to bending loads. There are three types:
- Endwall Columns These are found at either end of the building and are the primary support structures for the endwalls, and in some case the entire building. Depending on the width of the building, there may be several columns.
- Endwall Rafters Like the endwall columns, they are found at either end of the building providing support for the roof.
- Endwall Girts Endwall girts are placed along the endwall and bolted to the endwall columns. They provide extra support for the endwalls and are where you screw in the endwall panels.
Everything you want in a metal roll-up door – durable construction, quiet operation, and long-lasting performance – you’ll find in the Roll-Up doors from Mueller. Every door comes practically pre-assembled, with the steel bottom bar and locks already in place. Once you install the mounting bracket, you’re well on your way to completion. We offer several types, including mini-doors, low-profile, commercial or heavy commercial doors. Select from a wide range of sizes and designer colors so your building can maintain a uniform look while still providing accessibility to meet your needs. Mounting hardware is also included.

Walk doors can use standard, premium, heavy-duty lever locksets or panic hardware. Weatherstrip kits are recommended to give you a tighter fit and reduced air leakage and dust. You can order complete door kits, which include the door, frame kit and standard lockset. Doors are 20-gauge steel with a polystyrene core, and frames are 16-gauge steel. A slide bolt is included on the 6' x 7' door unit.
Steel Building Trim
Our trim packages give your steel building a finished, customized appearance:
- Peak Sheet/Ridge Roll: Found at the peak of the building – used to seal the joint where the two sets of roof panels meet.
- Rake Trim: Found at either end of the building – used to seal the joint where the roof meets the endwall.
- Corner Trim: Found at the corners – used to seal the endwall/sidewall joints.
- Eave Trim: If your roof panels end flush with the sidewall, you need eave trim to seal that joint.
- Gutters: On a building requiring eave trim, gutters can be used to not only seal the joint, but also to control the water off of the roof.
The most common product used to insulated our steel buildings is 3" reinforced fiberglass insulation. We offer custom cut lengths, varying thicknesses such as 4” and 6”, and many different facings to choose from. Solarguard insulation addresses all three forms of heat transfer. It has a fiberglass core to slow heat transfer through conduction and convection, plus a highly reflective foil backer film to block radiant heat as well.
Our fiberglass reinforced plastic (FRP) panels, made of polyester resin, allow for natural sunlight to help illuminate your building.
Windows for your metal building provide both light and ventilation. Mueller self-framing windows are 3’ or 6’ wide and 3’ tall. Available in both standard or insulated models, our windows slide horizontally and require no special framing in the building. Click here to watch window installation tips.
Mueller manufactures commercial and low-profile vents. Our low-profile ridge vents control air flow through the building while providing a sleek, streamlined appearance with the roof. Available in many designer colors, ridge vents are an excellent way to remove heat from your building. Installed at the ridge, they allow the warm air inside a way to escape and also help manage condensation and moisture. Ridge vents come in 10' lengths. You can also achieve low-volume air movement by installing Mueller-made wall louvers.
For all metal to metal applications, carbon steel self-drillers are used. Our drillers have a tapered compression point and flat-top design, which combines the under-cut hex washer heads with EPDM sealing washers. Long-life fasteners with a zinc alloy head offer a lifetime warranty against red rust. They are commonly used in coastal regions, where moisture and humidity can cause corrosion. Woodgrip screws are a metal to wood fastener designed to self-drill metal panels and tap into the wood beneath. Our 1/4" hex head woodgrips provide quick engagement and exceptional pull out strength. Low-profile fasteners feature an aerodynamic design, providing an aesthetically pleasing alternative to a hex-head screw. They were specifically designed to provide a sleek appearance with all Mueller panels.
