Serving the marine and construction industry with integrity since 1975, Marine & Construction Supplies is a wholesale distributor of watertight doors, watertight hatches, manholes, scuttles and portlights from Cen-Tex Marine Fabricators. We also distribute fire-rated doors, joiner doors, hollow metal doors, and bullet and blast-resistant doors from Deansteel. Our specialty is solving problems for our customers, even if it requires us to go out and find a new product, or create a custom design. For example, our customers wanted a reliable source for marine windshield wipers, and we met those needs by representing Speich and Sprague wiper systems. We only represent the finest-quality products that we are sure you can depend on.
