Aluminum Grating
Aluminum grating is an excellent choice if your project needs some corrosion resistance, rust resistance, and a high strength option at a relative lower cost. If your project incorporates lots of corrosives or damp areas, then aluminum grating may be the way to go. Aluminum grating matches light duty grating in all its properties, sizes, and finishes. Many common uses are in treatment plants, oil wells, platforms, and walkways. Give our sales team a chance, and we can help you find the perfect option.
