Grate covers for drainage ditches, made from steel grating, are available in various models to accommodate different span loads and requirements. Widely used in municipal roads, garden facilities, residential communities, schools, sports fields, and other venues. Depending on the application, different specifications and models of grate covers can be hot-dipped galvanized, cold galvanized (electroplated), or untreated.
Grating covers are primarily used in factories and residential communities due to the frequent crushing of concrete trench covers and the resulting damage to road surfaces. Steel grating covers are designed to accommodate various load capacities. They are simple to install, lightweight, have excellent load-bearing capacity, are impact-resistant, bend rather than break, have high drainage volume, and are aesthetically pleasing and durable after hot-dip galvanizing treatment, offering corrosion resistance and superior advantages over cast iron covers. Additionally, with hinge connections or hook connections, they are easy to open and feature anti-theft capabilities. They are widely used in factories and residential communities.
Product Material:
Flat Steel: Made of Q235A or stainless steel, available in plain, anti-slip toothed, and I-section profiles. Common sizes include 20*5, 25*5, 25*3, 32*5, 32*5, 40*5, 40*3, 50*5, 65*5, 75*6, 100*8, 100*10, etc. Due to direct factory sales by Jianji, a wide variety of specifications are available.
Rod: Round steel, twisted square steel, square steel, or hexagonal steel made of Q235A or 304 stainless steel. Twisted square steel is produced by drawing through square dies from round steel coil and then twisting, with common sizes including 5*5, 6*6, 8*8mm, etc.
Concrete: Reinforced concrete material with strength reaching C25/C30/C35. High load-bearing capacity, low cost, and easy maintenance.
Product Features:
1. Aesthetically pleasing: sleek lines, silver exterior, modern trend.
2. Drainage: Leak area reaches 83.3%, more than double that of cast iron.
3. Hot-Dip Galvanized: Strong corrosion resistance, maintenance-free and replacement-free.
4. Anti-theft Design: Hinged connection between the cover and frame, providing anti-theft security and ease of opening.
5. Cost Savings: Larger spans, under heavy loads, are more cost-effective than cast iron, and save on the expenses of theft or crushing replacements.
6. High Strength: Offers significantly higher strength and toughness than cast iron, suitable for environments with large spans and heavy loads, such as docks and airports.
7. Various specifications: Satisfying the needs of different environments, loads, spans, sizes, and shapes.
Product Application: This product is easy to install, lightweight, has good load-bearing capacity, is shock-resistant, prefers bending over breaking, has high drainage volume, and is aesthetically pleasing and durable after hot-dip galvanizing treatment, offering corrosion resistance and superior to cast iron covers. It can be connected with hinges or hook-type connections for easy opening and features anti-theft capabilities.
