Round Steel Welded Bar Grating For Industrial Catwalk Grating , 16 - w - 4
Parameter
Press-locked grating is also called pressure locked grating or press-locked steel bar
grating. Basically, the press-locked grating have the same load
capacity with the welded steel bar grating. The difference between
press-locked grating and welded steel bar grating are joint
connection technology and cross bars.
Cross bars of welded steel bar grating are twisted square rods and
the bearing bars are rectangular bars or I type bars. Both the
bearing bars and cross bars of press-locked grating are rectangular
bars.
Compared to welded steel bar grating, which is produced through
resistance-welding process, the press-locked grating is constructed
with the two close-tolerance slotted bars bonded together by
tremendous hydraulic pressure. This production can let press-locked
grating be a permanent locking.
Press-locked grating and swage-locked grating has excellent lateral
stiffness, which can be used in some special applications. And the
serrated surface is available for press-locked grating.
Specification:
- Materials: low carbon steel and stainless steel.
Surface treatment: galvanized, painted or powder coated.
Surface type: smooth surface and serrated surface
Serrated surface type:
PR/S1: Trapezoidal teeth on the bearing bar.
PR/S2: Trapezoidal tooth both on the bearing bar and cross bar with the highest non-slip performance. In this three types. it is most popular.
PR/S3: The non-slip tooth is applied to the connect components. It has the lowest non-slip performance.
Bearing bars and cross bars are notched and have same height. | Bearing bars are higher than the cross bars,bearing bars are
notched. |
Bearing bars are higher than the cross | Notch on the bearing bars are at a angle of 30° or 45° |
High strength and high bearing capacity:
- Non-slip, anti-corrosion, not easy to deform.
High safety performance.
Do not accumulate rain, snow and dust.
Simple and beautiful appearance.
Easy to install and remove to extend the lifespan.
Applications of serrated welded steel grating - Serrated welded steel grating is widely used as platforms, stair treads, walkaways and floors in industrial, civil and commercial buildings.

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.

Introduction of hot dip galvanized steel grating
1>Material:carbon steel or stainless steel
2>Cross bar pitches:maybe 24-200mm,of which 50mm,76mm and 100mm are recommended.
3>Steel grating is made by the world first-class equipment,which can arrange the bearing bar and cross bar in longitude and latitude order to certain distance.cross bar is pressed into the bearing bar by high tension resistance weldingring which is controlled by computer.so we can produce high quality gratings with firm welding,smooth surface and high strength.
4>Surface process of steel grating:Types:hot-dipped galvanized,electro-galvanized ,spraying brushing. 95% people choose hot-galvanized because its anti-acid and alkali corrosion capacity range is from PH6 to PH12.5,a stable protective film will be formed on the zinc surface.it has good anti-corrosive property.
5>Attractive appearance:Simple outline.silver colour and modern.
6>Optimum water draining:Water leakage area reaches 83.3%,which is more than two times larger than that of cast iron.
7>Hot-dip galvanizing:Good antirust performance,maintenance free and replacement free.
8>Design of preventing theft:The cover is connected with the frame by gemel,which ensures protection against theft,safety and convenient opening.
