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.
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.
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.
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.
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.
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.
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.
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.
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.
General Steel Rigid Frame
- Anchor bolts, foundation designs and erection are provided by others
- For purposes of quoting, the weights listed for each live load can be used for other building codes used in the United States, (i.e. BOCA, SBC, UBC etc.)
- If you have any questions about whether these buildings can be utilized for your customer’s specific code requirements or if any adjustments are necessary please contact General Steel.
