SURFACE TREATMENTHot dip galvanized, Untreated, Painting, Electrostatic sprayingTECHNOLOGYPress-Locked Gratingis specified due to its clean, smooth look as well as supporting the same loads as welded bar grating though not recommended for rolling loads. Press-Locked is formed using tremendous hydraulic pressure to bond the two close-tolerance slotted bars together, permanently locking the cross bars into the notched bearing bars. Press-Locked grating is fabricated to meet project requirements. Press locked bar grating is an extremely versatile product that can be used in a wide range of industrial applications. It offers the advantage of superior lateral support, particularly when using press-locked steel bar grating (as opposed to the aluminum version). What's more, press locked-bar grating is durable and very easy to maintain, making it a reliable and long-term grating solution.The Uses ofPress-Locked Bar Grating1. Stair treads2. Security screens in commercial buildings3. Municipal engineering as tree covers, trench covers and drainage covers4. Platforms5. Walkways in industrial factories or parks6. Modular mezzanine structures7. Bridges for vehicles and pedestrians8. Marine industries as working platform9. Suspended ceiling
