America’s Largest Fabricator andErector of Light Gauge Steel

Trusses and Wall Panels

Transportation to the jobsiteSuperior Truss & Panel offers a complete package including manufacturing, installation and transportation. We own

and operate our private fleet of trucks. As such, dependable on-time delivery to your job site is assured, and the risk

associated with transferring our material to a common carrier is eliminated. We control the entire process from planning,

manufacturing, transportation and installation.

This aids in higher quality product transported and

installed by the company that built it. The same

high quality that leaves our facility will be delivered

to your site, ready for installation.

WeatherDon’t let your project get held up because of

weather conditions. The very nature of our

material allows for ease of installation in most

weather climates. In addition to the many

benefits of light gauge steel, our roof trusses

can be installed during many climate

conditions which will aid in the erection and

enclosing your structure quicker.

We take pride in controlling the entire process. This ensures our customer receives the highest quality available along with the pieceof mind knowing that they have one supplier handling everythingon their behalf. The need for multiple subcontractors is eliminated,thus aiding in efficiency.

of Light Gauge Steel Trusses and Wall Panels

InstallationPurchasing your light gauge steel roof trusses from Superior Truss & Panel is only half the task. Allowing our dedicated crew to install the trusses will ensure the job is completed right the first time. Installation is an optionalservice offered, but we are sure you will be glad you chose Superior Truss to complete this portion of your project.

We take pride in controlling the entire process and rendering a Superior product and service. We work with youfrom design, manufacturing, installation and transportation. Superior guarantees our work and you will have peaceof mind knowing your roof trusses were installed correctly the first time.

Bracing and ErectionDuring the installation phase,

proper construction and

permanent bracing are the

major keys to a successful

erection. Improper bracing is

the leading cause for collapsed

trusses during erection.

Superior takes pride in its

bracing techniques and has

adopted the guidelines as

published by the Light Gauge

Steel Engineers Association

as its installation guidelines.

Proper installation bracing depicted above which will guard against buckling, bending and collapse.

America’s Largest Fabricator and Erector of

Engineering Services provided byMiTek¤ Industries, Inc.Superior Truss is willing and able to provide the

engineer of record with a manufacturer that has

the ability to take the full engineering responsibility

for their product. Our engineering services,

provided by MiTek® Industries, Inc., can include

an engineering stamp for the complete roofing

system in all 50 states. This stamp, will ensure

the design has all the elements outlined in

the specifications.

We will provide a Complete Structural Roof System”Does your light gauge steel roof consist of the

following components? If not, it may not meet

building code requirements.

q Light gauge steel trusses

q Truss permanent and installation bracing

q Truss connections: truss to truss & truss to structure

q Roof deck assembly

q Roof deck shear transfer framing

q Eave edge structural supports

q Valley, hip and ridge structural supports

The 7 elements above form a Complete Structural Roof System”Through MiTek®’s engineering, we will provide the following to ensure your roof meets the code:

1. Light gauge steel trusses that support vertical loads both up and down, transfer of

lateral loads and provide proper bearing for roof and floor decks.

2. Truss permanent and installation bracing to prevent chord and web buckling.

3. Truss connections that resist gravity, wind and seismic loads.

4. Roof deck assembly that supports both uniform and concentrated vertical loads; the

deck also acts as a shear diaphragm resisting seismic or wind loads.

5. Shear transfer framing that collects roof deck shear and transfers it to the building structure below.

6. Eave edge structural supports that collect shear from the roof deck and supports concentrated

and uniform loads at the roof edge

7. Valley, hip and ridge structural supports that transfer shear across the roof deck transition planes

and supports the concentrated and uniform loads.

A light gauge steel structural roof system consists of:
