Synthetic Webbing Tie Downs WSTDA-T-1

Synthetic Webbing Tie Dows: Any combination of fittings, webbing and tensioners forming an assembly that attaches
to vehicle and cargo anchor / attachment points. Tie downs are used for securing articles of cargo to a vehicle or restraining articles of cargo from movement on a vehicle.

WORKING LOAD LIMIT: The maximum allowable loading force for each web tie down.

The design factor for new synthetic web tie downs, with or without hardware,  shall be a minimum of 3:1

WEBBING: A fabric, woven of high tenacity yarns offering suitable characteristics for use
in the manufacture of web tie downs. Reference the WSTDA Recommended Standard Specification for Webbing used for Tie Downs (WSDTA-T-4)

TREATED WEBBING - Webbing to which a chemical treatment has been applied which offers some degree of protection against an environmental or mechanical hazard.

UNTREATED WEBBING - Webbing without any additional chemical treatment or coating.

Polyester webbing is typically used in systems where low elongation and low creep are desirable. Polyester’s higher density allows thinner webbing than nylon (at equal strength). Polyester webbing has better natural resistance to moisture than nylon, although some over coatings allow approximately equal performance of both types. Polyester is generally more resistant to acids than nylon.

Nylon webbing is also used in many applications where shock absorption properties are important because nylon webbing has higher elongation than polyester webbing of the same construction and strength. Nylon webbing has better natural abrasion resistance properties than polyester webbing, although some over coatings allow approximately equal performance of both types. Nylon is generally more resistant to most alkalis than polyester.
