Butt Welded or Full Welded Trench Grate or Drain Cover for Plaza Drainage System
Description:
Drain cover is usually used in the side of the road and swage treatment plant, it is for water drainage.Trench Drain Cover Gratings are steel lattice panels formed with simple lines, secured with hinged lid and connection. Ideal replacement drainage covers for conventional cast iron materials. Suitable for light type and large span heavy loading environment. Widely used in sewage treatment system in urban roads, squares, gardens, docks, airports, parking lots, roads, railways, industrial engineering and other types of industrial buildings.
Trench cover is another usage of steel grating, it's usually used in drainage system, like sewage treatment plant, port drainage channels, and plaza drainage system. As our products are mostly hot dip galvanzied, it can resist corrision and rust. Moreover, we can produce different size of steel grating for customers according to different load capacity requirement, shape request, etc.
Feature:
Appearance: simple lines. Silver exterior, modern trends.
Best drainage: leakage area of 83.3%, more than double the cast
iron.
Hot-dip galvanizing: rust-proof and strong, maintenance and
replacement.
Security design: box with hinged lid and connection, security,
safe, easy to open.
Saving investment: large span. When overloaded, the lowest ratio of
iron and saves replacement costs stolen, then crushed.
High strength: strength and toughness is much higher than cast
iron, can be used for terminals, airports and other large span and
heavy load environment.
Specifications and more: meet different environment and loading
requirement. Span, the desired size and shape.

Application
1. Widely used in shipbuilding, harbor, oceanographic engineering, building, paper mills, cement plant, medicine, spinning and weaving.
2. Is applied in food stuff factory, transportation, municipal administration, parking lot , etc.
3. Also used by various plants such as electric power, petroleum,chemical industry.
Packaing
1. Strap Packaging: generally applicable to relatively neat grid of
steel plate.
2. Pallet Packaging: Usually for export packing.
3. Screw Rod Fixation: using four screws bar through the steel
grating aperture, with screw locking packaging methods.
WELDED GRATINGEconomical design ideal for most industrial applications. Manufactured by welding the bearing bar/cross bar intersection, typically with automated forge welding equipment. Available in carbon steel and stainless steel. | DOVETAIL PRESSURE LOCKEDPopular for the manufacture of aluminum, stainless steel, and close mesh gratings. Cross bars are inserted into pre-punched holes in the bearing bars and hydraulically deformed to lock the bars in place. | ||
SWAGED PRESSURE LOCKEDAssembled by inserting pre-punched bearing and cross bars into an “eggcrate” configuration and deforming the cross bars under intense hydraulic pressure. Available in all materials and ideal for architectural and ornamental applications. | RIVETED GRATINGExceptionally durable grating manufactured by riveting bearing bars and bent connecting bars at their contact points. Excellent for applications involving impact loads and repetitive traffic patterns. |
