Bar Grating Specifications

A proper design for bar gratings includes a determination of material, construction, loading conditions, unsupported clear span, surface treatment, finish, and edge banding. Carefully considering the application and environment will allow the sales staff at Peterson Company to help you select the products that will stand up to many years of tough service.

Materials & Finishes

Bar grating comes in many different materials and finishes. Aluminum, Carbon Steal, 304 Stainless Steel and Fiberglass are some of the material options, and mill (uncoated), painted with fast drying black enamel, or hot dipped galvanized (to meet ASTM Standard A-123), are standard finishes.
