Two standard surfaces are available: slottedsmooth and anti-skid. Anti-skid is the ideal choice when safe walking conditions are important. Dieformed teeth in the transverse ribs give you 360° of shoe-gripping traction even when the grating is wet, oily, muddy, or icy.
Punched Interlock Grating has an open area of 42% for 9' grating and 35% for 6' grating. This prevents dirt, debris, ice, and snow from building up on the surface and allows light and air to pass through. United Interlock steel grating is made from pre-galvanized steel which conforms to a G-90 thickness designation per ASTM A653. The aluminum grating is made from type 5052 aluminum with a thickness of 0.080'.
Unpunched smooth surface grating is also available for special applications.
Sep 14, 2017 Unistrut nuts are available with a variety of hole sizes, to accept a range of hex head cap screw (hex bolt) sizes. There are even spring nuts with bolts built in; these are called stud nuts, and they can make the assembly process very quick and efficient.

One of the most common requests we receive concerns drawings for Unistrut support structures.
The tables below contain downloadable standard design detail drawings for typical Unistrut applications–medical supports, rooftop walkways, and ceiling grid systems.
Please Note: Drawings below are generic details to show design intent only. The drawings will help you gain a better understanding of engineered system design options, but these drawings are not intended for construction purposes because each system is application specific. We are currently working on developing additional standard details for other systems, but at this time, we only offer resources to support the development of medical supports, rooftop walkways, and ceiling grid structures.
For interior applications, rooms will more than likely contain suspended MEP and we may need to make modifications to an existing design to accommodate mechanical systems such as plumbing, HVAC, and electrical. Contact Unistrut Service Company for pricing on site specific engineered system drawings.
