Load Bearing panels are built to provide superior structural integrity to your project in a very short time frame.

Load Bearing
Basic Metal Stud Assembly
Prefabricated Load-bearing walls

Basic cold-formed steel panels complete with all rough openings, headers, and bridging. Load-bearing panels are manufactured in a compression table to get the strength needed to support the diaphragm of the building. All panels are manufactured in a quality-controlled shop. Mammoth's scope typically includes exterior, demising, and corridor walls for load-bearing projects. To learn more about this system, please visit our Strategic Partner's website.

Load Bearing
Sheathing / Air Vapor Barrier

Exterior wall panels are built with a basic stud assembly, and sheathing is included on exterior panels only. The gypsum board installed on the walls can be any specified exterior drywall. Mammoth also can install weather barrier in our shop.  All panels are manufactured in a quality-controlled shop. Mammoth's scope typically includes exterior, demising, and corridor walls for load-bearing projects. To learn more about this system, please visit our Strategic Partner's website.

Load Bearing
Brick Tie Backing Plates for Brick Edge

An element designed to simplify the scope across trades. Brick ties are strategically placed throughout the exterior of the design to simplify masonry work performed in the field and guarantee consistent quality.
