General Steel Brand Buildings

Standard Features

General Steel brand buildings are for business owners who need to expand as well as individuals looking to grow their personal assets. Our brand of steel building is the highest quality pre-engineered metal building available in the market today. Therefore, General Steel buildings hold their value and have the foundation to appreciate at a more rapid pace compared to other construction options you may be considering. This is why thousands and thousands of Americans have chose General Steel when it’s time to build.

Versatility in Design

Technical Metal Building Information

Outlined below are the standard features you will receive when you choose to purchase a General Steel brand building. The technical aspects of our framing and how our buildings are fastened tightly together set our brand apart from the competition, while the warranties provided with your General Steel building show that as a company we stand behind the quality that our brand image represents. Our quality is just one of the many reasons why large corporations such as Dow Chemical, Boeing, NASA and General Motors choose General Steel.

General Steel Primary Building Framing

Solid I-Beam Construction for Optimum Strength of Your Building

By using a higher yield strength material, a smaller web can be utilized which provides for a space saving design. General Steel building frames are single bead; continuous submerged arc welded by automatic welding machines (this helps insure quality control). A factory primer coat is applied to help protect the steel during the erection process.

End Wall Frames and Columns

Your end wall frames and columns are either cold formed, mill-rolled or built-up “I” sections depending on your specific steel building design requirements.

General Steel Secondary Building Framing

Girts (in sidewall)

Are 8.5” or 10” to meet design requirements, cold rolled Z-section, 13 to 16 ga. ASTM A-570, 50,000 or 55,0000 p.s.i. yield material is used to provide maximum strength. Bypass girt system overlaps at sidewall columns forming a continuous “beam” for extra strength.

Purlins (in roof)

Are 8”, 10”, or 12” to meet design requirements. In General Steel buildings your purlins are top-mounted on the rafter with a varied lap of 2’to 6’ for strength and cost savings in erection labor. Maximum purlin spacing is 5’ on center. Purlins also use a bypass system.

Eave Strut

Is a cold-formed C-Section that is rolled for the appropriate roof pitch to help insure that all General Steel buildings are weather-tight at the eave.

Sheeting Angle

Is a continuous angle supplied for the attachment of the sheeting at the rake of the building for ease of installation of General Steel buildings.

Base Angle

Is a continuous angle, supplied for the attachment of the base of the sheeting to the concrete. It is attached to the concrete with ram-sets or equivalent anchors by others.


For General Steel buildings either diagonal rod or cable bracing may be supplied for roof and walls to remove longitudinal load from the structure as needed.

Angle Flange Bracing

Is provided for the connection of the rigid frame 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.

General Steel Fasteners

Structural Bolts

Structural bolts used with General Steel brand buildings meet requirements of ASTM standards. ASTM Standards: A-325 for primary frame connections. A-307 for secondary framing.

Self Drilling and Self Tapping Fasteners

Are pre-assembled with neoprene washers and metal caps to help insure weather tightness of your steel building. This feature is one of many qualities that sets a steel building apart from traditional construction, steel buildings will not leak which prevents potential water damage.

General Steel Sheeting

80,000 p.s.i.

80,000 p.s.i. yield material is standard on General 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 (1.25oz – hot dipped) on each side helps prevent deterioration of the steel sheeting.

Deeper High Rib

Deeper High-Rib with more frequent corrugations, provides extra strength for the steel building.

Purlin Bearing Rib

The purlin bearing rib provides a better weather tight seal between the roof sheets on your steel building.
Optimal Semi-Concealed Panel “Shadow Line”

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

General Steel Building Sealants


For roof sidelaps, endlaps and flashing gable is provided to help insure weather tightness. Nominal 3/8” x 1/8” thick pressure sensitive tape sealant for ease of installation.

General Steel Buildings Trim and Flashing

Trimming and Flashing

Trimming at rake (gable) corners and eaves is provided for all General Steel buildings with standard trim material for a finished look. This is also a deterrent to moisture, insects, and dirt getting into the building.

General Steel Ridge Cap

Preformed High Rib Ridge Cap Panel

Matches the slope and profile of adjoining roof panels on General Steel buildings to help insure constant alignment and weather tightness.

Long Overlap

Is provided to help prevent water from siphoning into the building.

General Steel Building Plans and Drawings

Anchor Bolt Setting Plan

Demonstrates building reactions for all buildings with standard trim material for a finished look. This is also an additional deterrent to moisture, insects, and dirt getting into your building.

Engineer Certified Erection Drawings

Including wall and roof framing diagrams, cross sections, sheeting and flashing details are provided. These drawings show clearly the proper erection and assembly of all building components.

General Building Manual

Erection drawings provide step-by-step instruction for assembly of your building.

Part Numbers

Are placed on each component (other than screws). These part numbers coincide with a detailed listing contained in the construction drawings and shipping list to help with assembly of the building.
