Plug Steel Grating

Plug grating is a lightweight and durable flat steel structure widely used as
building material in civilian and commercial buildings, theaters, metro,
suburban railway and construction projects of various public works areas and
facilities. The grating is made with carbon steel or stainless steel bars going
through the opening (hole), plug, welding and finishing processes, galvanized
or stainless steel natural color.
Grating length
The bearing grating length is the external grating dimension measured in the
direction of the bearing rods (this applies even in the case that the grating
length is shorter than the width thereof).
Grating width
The non-bearing grating width is the external grating dimension measured in the
direction of the filling rods.
Bearing rods
The bearing rods are parallel grating chords supported on both ends and used to
transmit the forces induced by the grating load.
Filling rods
The filling rods are chords sized as a rule to 10 x 2 mm maintaining the
vertical position and stability of the bearing rods.
Mesh size
The mesh size is the axial distance between two adjacent bearing rods and two
adjacent filling ones.
Border band
The border band is a steel band used as a border and reinforcement of the
peripheral grating area; as a rule, the cross-sectional area of the border band
is identical with that of the bearing rod of the grating.

Unidirectional Anti-Slip Arrangement
Indentations cut out in filling rods creating an effective anti-slip grating
arrangement.
Bearing structure
Supporting structure, as a rule steel or concrete construction, where gratings
are anchored.
Cut outs
Rectangular, oblique and/or bow-shaped apertures in grating structures cut out
in accordance with the Customer drawing or sketch.
Step sides
Staircase step sides made from flat bars and used to screw the step onto the
staircase bearing structure (the string boards).
Feature: Plug steel grating has lightweight, high strength, corrosion-
resistance, it is strong, durable, maintenance-free, beautiful and a great
choice for use in both residential and industrial applications.
