Stair Pans are also known as steel stair treads or metal stair steps. We offer many types of metal stair pans based on the installation preference. Diamond Plate Stair treads are commonly used to build stairs that do not require a concrete fill and that need an anti-slip surface for safe foot traffic. At Omni Steel Supply we will make the stairs exactly the way you wanted it to be designed. We are a leading manufacturer and supplier of Diamond Aluminum Plate in New York.
