Water and wastewater treatment facilities are incredibly tough environments for doors. Caustic conditions rust out hollow metal doors in a matter of months. Laminated fiberglass doors can swell and crack on the edges. Weiland fiberglass doors on the other hand are molded all at once, so the actual fiberglass is seamless all around the door. This provides maximum durability and corrosion protection for water treatment facilities in food processing plants and municipalities.
