We have a cabin on the Mission River very close to the saltwater bays along the gulf coast of Texas. The waters are brackish with a much higher salt content than fresh water. Everything that is metal will assuredly rust. Aluminum corrodes and nylon screens will never last in this rugged environment. Needed something like stainless steel to do the trick. Couldn’t find anything local so I searched the web and found Metro Screenworks. Took the plunge and ordered a roll big enough to do a very large screen porch. Very outstanding quality and super easy to work with. Looks almost invisible when installed & feels very durable. Bugs and birds fly into it & bounce off of it like a trampoline. The mosquito invasions are totally baffled as well. Although being very expensive, it was worth every stinking penny. If ever needed again, I will buy this product again in a heartbeat.
