Gutter cover

1. Gutter Cover Introduction

Grate covers, also known as "manhole covers," "sandwell covers," or "sewer covers," are made by pressure welding steel grating plates. They offer simple installation, lightweight, excellent load-bearing capacity, strong impact resistance, and good drainage. The surface is treated with hot-dipped galvanizing for aesthetics and corrosion resistance, providing superior advantages over cast iron grate covers.

2. Drainage cover types

Anti-theft rainwater trench cover: This type of roof drain cover steel grating is commonly used in unmonitored areas        U-shaped manhole cover: Designed for easy and quick installation, tailored to various construction requirements, Pu

Outdoor area, commonly found along highways, parks, and dock sides for play. Surroundings enhanced        The coating of Tonggang grating is made of angle steel. One side of the angle steel is welded to the steel grating.

Angle steel frame pads, steel grating, and angle steel frames are fixed with hinges and other methods, allowing for self-assembly.        One side serves as a support edge and impacts the groove side. The manhole cover is easy to install, and no need to cut the groove edge.

Reversed. Angle steel frames are typically embedded in concrete with embedded parts, whereas amateur thieves generally...        Ditch. It is easy to open and clean.

Not movable.

Standard Grated Manhole Cover: This type of manhole cover requires a trench to be reserved during the planning stage. Rainwater Grated Manhole Cover: It is a simple and cost-effective type of manhole cover. Can be installed in channels and ditches.

Types of manhole covers are easy to manufacture and affordably priced. This type of cover is widely used on urban drainage ditches to form lids. These lids ensure excellent drainage performance while also providing...

Roads, squares, gardens, docks, airports, parking lots, highways, railways, industry... Allow for vehicle passage. Galvanized angle frames provide large openings and accommodate grilles.

Engineering and various industrial and civil buildings.  Strong base. It can bear the load of steel grating, enhancing the load-bearing capacity of the grating.
