1/2" webbing for bridge hammocks

[Spaceman]

I'm getting ready to try my first DIY bridge and have been researching sources for the 1/2" polyester webbing commonly used along the sides. Is there a minimum breaking strength I need to look for? Do I need something with a breaking strength >1000lb, comparable to the amsteel used in the rest of the suspension, or is there less force at work here? Strapworks has 1/2" polyester with a 1800lb breaking strength (600lb working load) and a polypro with a 450lb breaking strength (150lb working load). Considerable price difference (.41/ft vs. .13/ft), but I'm assuming I need the heavier stuff. Any other good sources besides Strapworks? I saw some at DIY Gear Supply, but it was white.

There are two sides, so two straps, plus you're rolling the fabric around the webbing, so you have 3 layers of fabric reinforcing each strap. I'd say that makes the polypro strong enough. Others may disagree, though, so do what you feel comfortable with.

I have used Strapworks' 1/2" polyester webbing and the 1/2" tubular polyester webbing from DIYGear.

Personally I would avoid polypropylene. It is only marginally strong enough, has low abrasion resistance (think about the connection to the spreaders and suspension triangles) and only saves ~$3.00-$4.75 on a bridge hammock. I don't want to be thinking about the webbing end connections a year after I made it for $3.00-$4.75.

I prefer the tubular DIYGear webbing. It is soft and easier to sew through multiple layers.

I used the polyester from Strapworks in mine .. Lower stretch, more abrasion resistance, less water absorption . Take advantage of their grab bag offering too ..
