WE UNDERSTAND FABRIC

At Calhoun, we understand fabric. We understand the mechanics of fabric and we understand the properties of fabric. We don’t make assumptions and we don’t treat fabric like rigid steel panels.

Many fabric structure companies fail to take an in-depth look into the mechanics of fabric using a linear analysis. This means that when the fabric is under pressure from the weight of snow or other environmental elements, the fabric moves in exact proportion to the amount of load applied. If the load doubles, the fabric moves twice as far.

A common contributor to increased wear and tear on fabric is when fabric companies apply a linear analysis when engineering their fabric structure, causing the fabric to bow and take a shape in indirect proportion to the weight of environmental loads. This results in unnecessary repairs and replacements, sooner.

Calhoun is unique in that we have developed specialized analysis which models the shape of fabric under load. By accurately determining various environmental loads that are applied to your steel structure, we use a non-linear analysis. Calhoun’s approach ensures the optimal design of the steel is determined for your structure, reducing total cost.

Key Features:

  • CAN EXCEED 150 MPH WINDS
  • CAN EXCEED 300 LBS PER SQUARE FOOT SNOW LOAD
  • FEATURES UP TO 16% TRANSLUCENCY ON NON-FR FABRIC AND 19% TRANSLUCENCY ON FIRE-RETARDANT FABRIC

LARGE STRENGTH-TO-DENSITY RATIO

Calhoun’s fabric covers are made of engineered high-density polyethylene (HDPE) fabric manufactured from 12 oz per square yard in weight, and 24 mil thick.
Known for its large strength-to-density ratio (which can range from 930 to 970 kg/m3), HDPE provides stronger intermolecular forces and tensile strength than other tensile fabric membranes.

HDPE fabric is manufactured into a woven sheet-form and then coated on both sides with a specialized, thick protective layer that aides in protecting against UV damage. HDPE offers increased protection against abrasion during fabrication, installation, and everyday use.
