General Steel Buildings - Standard Features |

General Steel Building Primary Framing
Solid I-Beam construction for optimum strength of all General Steel buildings.
- By using a higher yield strength material, a smaller web can be utilized which means 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 are either cold formed, mill-rolled or built-up "I" sections depending on design requirements. |

General Steel Building Secondary Framing
Girts (in sidewall) and Purlins (in roof) are 8" or 10" to meet design requirements.
- Cold rolled Z-section, 13 to 16 ga. ASTM A-570, 50,000 or 55,000 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 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.
Eave Strut is a cold-formed C-Section that is rolled for the appropriate roof pitch to help insure the General Steel buildings are weather-tight at the eave.
Sheeting angle is a continuous sheeting angle supplied for the attachment of the sheeting at the rake of the building for ease of installation.
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. (Base trim optimal).
Bracing 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.
