Our steel buildings come with many features including, sheeting, primary and secondary framing, sealants, and more. Below are further descriptions to all the steel building standard features. Find out why Anthem Steel is a leading steel supplier in North America.

Primary Framing

Solid I-Beam construction for optimum strength
  • By using a higher yield strength material, a smaller web can be utilized which provides for a space saving design.
  • Anthem Steel building frames are single bead; continuous submerged arc welded by automatic welding machines.
  • A factory primer coat is applied to help protect the steel during the erection process.
Solid I-Beam construction for optimum strength
  • Are either cold formed, mill-rolled or built-up “I” sections depending on design requirements.

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 that all Anthem Steel buildings are weather-tight at the eave.
  • Sheeting Angle: Is a continuous 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.


  • 80,000 p.s.i. yield material is standard on Anthem Steel buildings. Some suppliers use a lower yield strength material, which is less resistant to damage from hail and other impacts.
  • All Coil Steel with Galvalume coating standard (1.25oz – hot dipped) on each side helps prevent deterioration of the steel sheeting.
  • Deeper High-Rib with more frequent corrugations, provides extra strength.
  • Purlin Bearing Rib provides a better weather tight seal between the roof sheets.
  • Optimal Semi-Concealed Panel”Shadow Line” configuration is available for walls, mansard systems, soffit material, etc.., to add an aesthetic appeal to your Anthem Steel building.


Structural Bolts meet requirements of 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.


Closed Cell Neoprene Strips or plug with self-adhesive backing are used to help seal all Anthem Steel buildings.
  • Located at rake and roof-line of building to help provide weather tightness.
  • Optional eave and base closures may be added.
  • Pre-formed shapes to match panel configuration providing a tighter seal.


  • Sealant 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.

Ridge Cap

  • Preformed High-Rib Ridge Cap Panel: matches the slope and profile of adjoining roof panels on Anthem Steel buildings to help insure constant alignment and weather tightness.
  • Long Overlap: is provided to help prevent water from siphoning into the building.

Trim and Flashing

  • Trimming at rake (gable) corners and eaves is provided for all Anthem Steel buildings with standard trim material for a finished look.
  • This is also an additional deterrent to moisture, insects, and dirt getting into the building

Plans and Drawings

  • Anchor Bolt Setting Plan: building reactions for foundation design and Engineer Letter of Certification are provided shortly after receipt of deposit on building.
  • Building Manual: and erection drawing provide step-by-step instructions for assembly of Anthem metal buildings.
  • 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.
  • Part Numbers: 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.

Notes and Considerations

  • Anchor bolts, foundation designs and erection are provided by others.
  • If you have any questions about whether our steel buildings can be utilized for your customer’s specific code requirements, or if any adjustments are necessary, please contact the leading steel suppliers’ customer service department at Anthem Steel.
