We at Island Wide Screens use only the highest quality material at a discount price, in order to accomplish this, we buy the finest grade aluminum and screen cloth at bulk rates to pass the savings on to you! We have done our homework so you don't have to. Our Screen frame is .025 gauge aluminum the strongest on the market. The other guy's use .020 that makes us 20% stronger. Wether you live on the water or inland we know that our climate needs special consideration,over years of experience we have learned that the breakdown comes from the acceleration of corrosion caused by metal screws driven into the corner brackets of sliding screen doors. We have eliminated this problem by using only extruded aluminum corners that means no screws. This Screen Door will be your last.
