Quality Steel Grating Drain Covers
Drain Cover Description:
Drain covers are manufactured by steel gratings with various types for choice suitable for different spans and loading. They are widely used in municipal engineering, roads, gardens, residential districts, schools, stadiums etc. Surface can be hot dip galvanized, cold galvanized or with no treatment.
Features of drain covers:
1.Good appearance: simple line, silvery surface, modern design.
2. Optimized drainage effect: water leakage area upto to 83.3% which is twice of the iron castings.
3. HDG: superior rust protection, free of maintenance and replacement.
4. Anti-theft design: Covers and frames are connected by hinges providing safe and convenient application.
5. Save project investment: lower price and lower maintenance cost compared to iron castings.
6. High strength: higher strength and durability than iron castings, suitable for using in larger spacing and heavier loading conditions such as the docks and airports.
7. They are available in various types to satisfy the need for different environment, loading, spacing, and configuration.
