Glossary of Terms

A quick definition of industry terminology


A single piece of square tubing bent to shape to make the roof of the building. Bows are connected to the building’s legs and hold the panels on the roof. Bows are standard on buildings between 12′ and 24′ wide.

Corner Braces

Often referred to as leg braces, corner braces are U-shape steel channels attached to the legs that are used to help reinforce the structure of the building.  On all buildings, depending on the size, either four 2 feet or four 4 feet long corner braces come standard and they are installed on each corner of the building. Additional corner braces are available at an additional cost. We recommend the use of 2 feet long corner braces on each building leg (2 per bow). For buildings with legs that are taller than 8 feet, we recommend that customers upgrade to 4 feet long corner braces we also recommend that they be installed on each leg of the building (2 per bow).

Concrete Anchors

Sometimes referred to as concrete wedge anchors, concrete anchors are fasteners designed to attach a building to concrete. The concrete anchors are fastened into pre-drilled holes in the base rail and once in the concrete expand with an outward force against the walls of the concrete. Once expanded, the anchor wedges itself securely in the concrete.

Gable End

A steel panel, installed horizontally or vertically, with the same shape as the bow of the building. They can be installed on either end of the building and they extend from the 3 inches below the top of the legs, upward. Gable ends can be installed vertically at an additional cost.


Refers to the thickness of the panels and tubing used on the buildings. The lower the gauge, the thicker and stronger the metal.


The vertically installed lengths of square tubing that connect the bows or trusses (the top) to the base rail (the bottom).

Mobile Home Anchors

An optional type of anchor that secures a building in an installation where concrete is not used. It consists of two discs at the lower end of the anchor helical in design. They are supplied at no cost on certified structures installed on the ground. They can be installed as an option on non-certified structures with ground installation at an additional charge.


Corrugated metal sheeting used as the roof of the building and to enclose the building. Standard panels are 29 gauge steel. They are 3′ wide and they are available in standard lengths of 21′, 26′, 31′, and 36′. They are available in 20 different colors. For an additional charge, 26 gauge paneling can be bought.

Regular Roofline

The regular style metal carport designs are made in the barn roof which is rounded on the sides. This is built with excellent protection from natural disasters and is the perfect metal carport design for the buyer looking for both basic protection and a price that is budget-friendly.

Safety J-Trim

Metal material used as decorative finish underneath extra paneling on the sides of carports (optional), around walk-in doors, garage doors, and windows to provide a finished appearance. Choose from 20 different colors.


A triangular shaped welded square tubing frame made of steel that is connected to the building’s legs and holds the panels on the roof. A truss is stronger than a bow and they are standard on buildings larger than 24′ wide.


Lengths of metal that form the frames of the structures. Squared tubing is used on all buildings. Tubing thickness is measured by the gauge of the steel. Click on the gauge term to learn more about it.

Vertical Roofline

The strongest of the three carport designs is the vertical due to the cross bracing so the metal can be attached to the roof along with the advantage of the rain and snow sliding off of the side. The vertical is the style that works best with gutters.
