Magnum Steel Buildings and Pre-Engineered Commercial and Industrial Buildings

Standard Features

Primary Framing

Solid I-Beam Frames - single bead; continuous submerged arc welded by automatic welding machines. By using a higher yield strength material, a smaller web can be utilized which means a space saving design. A factory primer coat is applied to help protect them during the erection process.
Endwall Frames and Columns - either cold-formed, mill-rolled or built-up “I” sections depending on design requirements.

Secondary Framing

Purlins (in roof) - 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.
Girts (in sidewall) - 8” or 10” to meet design requirements. Cold rolled Z-section, 13 to 16 gauge ASTM A-570, 50,000 psi yield material is used to provide maximum strength. Bypass girt system overlaps at sidewall columns forming a continuous “beam” for extra strength.
Bracing - diagonal rod or cable bracing may be supplied for roof and walls to remove longitudinal load from the structure as needed.
Eave Strut - cold formed C-section that is rolled for the appropriate roof pitch, to help insure weather tightness at the eave
Sheeting Angle - a continuous sheeting angle supplied for attachment of the sheeting, at the rake of the building, for ease of installation.
Base Angle - 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.

Sheeting

All coil steel with galvalume coating standard 1.25oz hot-dipped on each side.
80,000 psi yield material is standard for every building.
Deeper, high-rib sheeting with more frequent corrugations provides extra strength.
Purlin bearing rib provides a better weather tight seal between roof sheets.

Ridge Cap

Pre-formed High Rib Ridge Cap Panel - matches the slope and profile of adjoining roof panels to help insure constant alignment and weather tightness.
Long Overlap - provided to help prevent water from siphoning into the building.

Fasteners

Structural Bolts – meet all requirements of ASTM standards.
Self-drilling and Self-tapping Fasteners - pre-assembled with neoprene washers and metal caps to help insure weather tightness.

Closures and Sealants

Closed Cell Neoprene Strips or Plugs - with self-adhesive backing; used to help seal buildings.
Sealant - roof side laps, end laps and flashing at gable to help insure weather tightness.

Trim

Trimming – gable corners and eaves with standard trim material for a finished look.
Plans and Drawings
Engineer Certified Blueprints - wall and roof framing diagrams, cross sections, sheeting and flashing details are provided with a letter from a certified engineer.
General Erection Manual - provides step-by-step instructions for easy assembly.
Part Numbers and Components - part numbers coincide with a detailed listing contained in the construction drawings and shipping list to help with assembly of the building. Anchor bolt plans and building reactions for foundation design are provided.
