Features of the Product
Superior Drainage Performance: The open mesh design offers a very high water permeability area (usually more than 80%), which rapidly drains surface water and keeps flooding and slick floors at bay.
High Strength and Heavy Load-Bearing Capacity: Different specifications are available for various circumstances (heavy industrial areas, driveways, pedestrian areas), with flat steel serving as the primary load-bearing structure. The heavy-duty variety is fully capable of withstanding the continuous strain of huge vehicles and forklifts without breaking or deforming.
Superior Anti-Theft Performance Compared to Cast Iron: Steel gratings are made of low-carbon steel or stainless steel, have a low recycling value, and are typically fixed using mounting clips or hinges, which essentially solves the anti-theft issue. Conversely, traditional cast iron trench covers are frequently stolen because of their high recycling value.
Anti-slip safety design: The trench cover's surface is usually composed of serrated flat steel, which is highly recommended and offers dependable anti-slip protection in damp, greasy settings like chemical factories, car washes, and restaurants.
Sturdy and low-maintenance: Usually hot-dip galvanised before being sent from the factory, it has a very high resistance to corrosion and may stay rust-free for 20 to 50 years in harsh water or outdoors, negating the need for regular repairs.
Cost-saving: Steel grating is lighter than cast iron covers with the same load-bearing capacity, which drastically lowers logistics and installation costs. Additionally, because of its vast span, fewer angle steel or concrete beams are needed for trench support.
FAQ
Q1: How can one decide between conventional cast iron trench coverings and steel grating for drainage ditches?
A: Steel grating is highly recommended. Despite their hardness, cast iron coverings are quite fragile and can break quickly under big truck loads, which can result in injuries. Additionally, they are regularly stolen, which might result in dangers like "man-eating" wells and ditches. Steel grating is durable; it won't shatter under extreme pressure and has no recyclable value, which deters theft. Compared to cast iron, which only uses tiny pores for leaking, its drainage effectiveness is several times higher.
Q2: The width of my trench is 300 mm. Which steel grating width should I order?
A: To provide enough overlap support on both sides, the steel grating's width must be larger than the trench's width. Generally speaking, the overlap width should be at least 20 to 30 mm on each side. Consequently, it is advised to acquire trench coverings with a width of 350 or 360 mm for a trench width of 300 mm.
