Pre-engineered Steel Buildings Frame Designs

dSolid I-Beam construction for optimum strength
Building material used is minimum 50,000 p.s.i. yield strength (some manufacturers use 36,000 p.s.i. yield strength material, which is not as strong). By using a higher yield strength material, a smaller web can be utilized which means a space saving design.
Steel building frames are single bead; continuous arc welded by automatic welding machines (this helps insure quality control). A factory primer coat is applied to help protect them during the building erection process. End Wall Frames and Columns are either cold formed, mill-rolled or built-up "I" sections depending on design requirements.

Secondary Framing Girts & Purlins are 8", 10", or 12" to meet design requirements.
Cold rolled Z-section, 13 to 16 ga. ASTM A-570, 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 weather tightness at the eave.
Sheeting angle is a continuous sheeting angle supplied for the attachment of the sheeting at the rake of the steel or metal 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 and/or equivalent anchors by others.
Bracing diagonal rod or cable bracing may be supplied for roof and walls to remove longitudinal load from the structure.
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.
