Rigid Frame Steel Building Technical Information

Worldwide Steel rigid frame steel building systems are manufactured in AISC- MB and ISO 14001:2004 certified facilities. We are dedicated to protecting our environment and reducing waste. In order to be awarded an ISO 14001 certification, our facilities underwent a rigorous auditing process by an accredited firm. This demanding process takes about a year to achieve, but is an extremely worthwhile investment to ensure our commitment to proper waste management and environmental protection.

An increasing emphasis on sustainability in the construction industry will involve the energy conservation and environmental impacts of construction. That’s why we prioritize our ability to design and produce energy-efficient buildings. In addition to these certifications, we prioritize sustainability by using all U.S. recycled steel in every Worldwide Steel Building.

Worldwide Steel Buildings offers a wide array of structural systems including clearspan rigid frame, modular rigid frame, tapered beam, and lean-to. All are available in standard or long bay options. Your building can be produced to virtually any desired dimension to achieve the optimal solution for your building requirements. All buildings are in accordance with the MBMA Metal Building Systems Manual and adhere to your specified buildings code.

Worldwide Steel Buildings also offers open web truss building packages in widths of 12′ through 100′ clearspan with side wall heights 8′ through 20′. Other sizes and heights available upon request.

Steel Frame Building Erection Manuals

We created our steel frame buildings with the do-it-yourselfer in mind. All Worldwide Steel Building trusses are pre-punched, easily bolt together, and have the purlin and girt clips factory welded for the easiest construction method. All steel purlins and girts attach to the clips with self-drilling screws. Your sheet metal attaches to the purlins and girts with colored, self-drilling screws that are flanged and self-sealing to prevent leaks, making frame construction and finish easy. Your steel structure kit also comes with a step-by-step erection manual to guide you or your local contractor from the start of your steel framing through the completion of your building.

Diagram of Rigid Frame Steel Building - Tapered Member Frame
These tapered framing members are typically used in clearspan situations from 40 ft. to 150 ft. It can be either gable or single slope. Common roof slopes of 1 in 4 to 4 in 12 are offered. When large clearspan areas are required for special industrial and commercial projects, the clearspan frame is typically the economical choice. The clearspan can be used with either cold-formed purlins or open web joists.

Diagram of Rigid Frame Steel Building - Solid Web Rigid Frame
The solid web rigid frame with interior columns provides multiple spans on wider buildings. It can be either gable or single slope. This frame type is economical with individual spans of 40 feet to 80 feet and building widths from 80 feet to 300 feet plus. Roof Slopes are 1 in 4 to 1 in 12.

Diagram of Rigid Frame Steel Building - Straight Column Rigid Frame
The straight column rigid frame is ideal for maximum efficiency of interior space. It is suitable for all types of small buildings that require clearspans from 20 feet to 60 feet. Roof slopes of 1 in 4 to 1 in 12 are available. The Tapered Beam frame is ideal for partitioning interior bays and small crane support systems.

Standard Rigid Frame Steel Building Features

Primary Framing

Solid I-Beam Construction for Optimum Strength of Your Building

Our designs use the highest yield strength material, allowing for a smaller web which not only provides a space-saving design, but a greater cost savings to our customers. Laser cut, pre-punched and sub-arc welded to ensure the highest precision.

End Wall Frames and Columns

Your end wall frames and columns are based on your specific building design requirements using either cold formed, mill-rolled or built up I sections to ensure it provides the greatest functionality.

Secondary Framing


8” or 10” based on design requirements. Cold rolled Z-section, 13 gauge to 16 gauge ASTM A- 570, 50,000 or 65,000 psi yield material used to provide maximum strength. By-Pass girt system over laps at sidewall columns forming a continuous connection for extra strength.


8”, 10”, 12” based on design requirements. Top mounted to your roof girders with a varied lap of 2’ to 6’ for strength and cost savings in the erection labor. Maximum purlin spacing is 5’ on center. Purlins also use the By-Pass system for maximum strength.

Eave Strut

Cold formed C-Section that is rolled for the appropriate roof pitch to help insure all Worldwide buildings are weather tight at the eave.

Sheeting Angle

A continuous angle supplied with every Worldwide building for the attachment of the sheeting at the rake of the building for ease installation of your sheeting and ensuring a weather tight seal along the gabled eave.

Base Angle/Girt with Trim

A continuous angle or girt supplied with every Worldwide building for the attachment of your sheeting to the concrete. This is easily attached with ram-sets or equivalent anchors by others and ensures a weather-tight seal along the base of your Worldwide building.


Every Worldwide building comes supplied with bracing in your walls and roof to prevent longitudinal loads and truss racking. This is accomplished by diagonal rod, cable, wind columns or portal frames based on your design needs.

Angle Flange Bracing

Provided with every Worldwide building to connect your rigid frames to the Purlins and Girts. This ensures that allowable compression levels are adequate for any combination of loadings.

Purlin bridging angles may be provided at each mid-bay to assure consistent purlin spacing and stiffening.

Structural Bolts

Structural bolts used with Worldwide buildings meet requirements of ASTM standards. ASTM Standards require A-325 for primary frame connections and A-307 for secondary framing.

Self Drilling and Self Tapping Fasteners

Pre-assembled with neoprene washers and domed metal caps to help ensure weather tightness of your steel building. This prevents leakage and prevents potential water damage. One of many features that sets a steel building apart from traditional construction.


80,000 psi

80,000 psi yield material is the standard on all Worldwide Steel buildings. Some manufacturers use a lower yield strength material, which is less resistant to damage from hail and other impacts.

All Coil Steel

All coil steel with Galvalume coating standard (1.25 oz – hot dipped) on each side helps prevent deterioration of the steel sheeting.

Deeper High Rib

Deeper High Rib with more frequent corrugation provides superior strength for the steel building.

Purlin Bearing Rib

The purlin bearing rib provides a better weather seal between the roof sheets on your steel building.

Optimal Semi-Concealed Panel

This configuration is available for walls, facade systems, soffit material, etc. to add an aesthetic appeal to your Worldwide Steel building.
