Covering

Sewn by Skilled Craftsmen

The fabric coverings on Span-Tech buildings are made from PVC, and sewn by people with over 25 years of experience in fine sewing craftsmanship. Our seams are double-stitched with high-strength bonded polyester webbing. The canvas can withstand up to 90 mile per hour wind loads.

Secure Tie-downs

Our smaller (24, 30, and 35 ft. wide) buildings have zinc plated D-rings attached with webbing and PVC belting. These, combined with a rope tie-down system, provide a neat, tight, secure installation, stretching the canvas over the rafters but keeps it away from the purlins. Rope hems add strength and stability.

Our wide buildings use piped hems and 5-ton lashing winches to make the covering tight, secure, and reliable.

High-Quality Fabric

We use twelve ounce per square yard material constructed of high density scrim, overlapped for superior strength, flatness and tear properties. A 2.5 mil coating is applied to each side for abrasion and pressure resistance and for seam integrity. Our fabric is UV-inhibited to minimize sunlight damage
