Material used is 34,000 and  55,000 p.s.i. yield strength. (Some manufacturers use only 34,000 p.s.i. yield strength material) Frames are single bead, continuous submerged arc welded by automatic welding machines to help insure quality. A factory-applied rust inhibiting primer is used to help protect the mainframes and secondary material during the erection process.


are either cold formed, hot-rolled or built-up “I” sections depending on design requirements.


GIRTS (in sidewall) and PURLINS (in roof) are minimum 8” to meet design requirements. Cold rolled Z-section, 12 to 16 ga ASTM A-653, 55,000 p.s.i. yield material is used to provide maximum strength.

Bypass girt system overlaps at sidewall columns forming a continuous “span” for extra strength. All girt clips are factory welded for easier erection.

PURLINS are top-mounted on the rafter with a varied lap of 1’6” to 5’ 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.

RAKE ANGLE is a 2×4 angle supplied for the attachment of the sheeting at the rake of the building for ease of installation.

BASE ANGLE is a 2×4 angle supplied for the attachment of the base of the sheeting to the concrete. The base angle is to be attached to the concrete with ram-sets or equivalent anchors.

BRACING All diagonal galvanized cable bracing is supplied for roof and walls to remove longitudinal load from the structure. Galvanized cable is used rather than solid rod to prevent the bracing from “sagging” under its own weight and it is easier to install. All cables are pre-stressed and pre made for easier erection.

Angle Flange Bracing is provided for the connection of the rigid frame to the purlins and girts. This insures the allowable compressions are adequate for any combination of loading.

FRAMED OPENINGS have cold-formed C-section jambs and headers to help insure easy installation of overhead doors, etc.


24 or 26 gage 80,000 P.S.I. yield strength material standard. Some manufacturers use a lower yield strength material, which is less resistant to damage from hail or other impacts. 40 year warranty on premium color finish on walls and trim. Roof finish is galvalume or premium colored finish

ALL COIL STEEL has a minimum of G-90 class Galvalume substrate (1.25oz hot dipped) to help prevent deterioration of the steel sheeting.

DEEPER HIGH-RIB SHEETING (PBR) with more frequent corrugations provides extra strength.


STRUCTURAL BOLTS meet requirements 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.


CLOSED CELL NEOPRENE STRIPS are used to help seal building. Located at eave, gable, and optional at the base of building to help provide weather tightness. Pre-formed shapes to match panel configuration providing a tighter seal.

1-1/2” SHEETING NOTCH at base of concrete where panel site is designed into every building. Sheeting notch provides an air infiltration stop on blanket insulated building.


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


LONG OVERLAP to help prevent water from siphoning into building.


All buildings are fully trimmed at rake (gable), corners, and eaves with standard trim material for a more finished look. This not only improves look of building, it is an additional deterrent to moisture, insects, and dirt from getting into the building.


ANCHOR BOLT setting plan, building reactions for foundation design, Erection Manual, and Engineer

Letter of Certification is provided shortly after receipt of deposit for building.

ERECTION DRAWINGS provide step by step instructions for case of assembly by dealer or customer.

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

ALL PARTS ARE NUMBERED A part number is placed on each component (not including sheeting,screws, etc.). These part numbers coincide with a detailed listing contained in the bill of materials that come with your building. They same numbers are also used on the drawings for clarity and to help with assembly on the jobsite.

26 Gauge – PBR Sheeting Profile (Purlin bearing Rib)

Factory Steel Overstock offers  standard  PBR panels, which have a larger overlap than R panels.  Some firms utilize an R panel for their roof sheets (picture on left).  Most pole barns and tube buildings use a lighter 29 gauge sheeting thickness.  For more information regarding building materials read standard specifications.

Fully Flashed Framed Openings

This feature truly enhances a steel building’s appearance.  Fully flashed framed opening means the trim is wrapped around the framed opening where you are unable to see the red-iron frames. The sketches to the right reflect this point.
