1. Brief Introduction of press locked steel gratings
With Press-Locked Grating the cross bars and bearing bars are
notched and pressed together through a high pressure manufacturing
process. The result is a bi-direction flush surface that assures a
firm, rigid connection and makes it aesthetically appealing for
architectural applications. It is available from stock in twp
bearing bars heights, in plain or corrosion-resistant galvanized
steel, or aluminum. A variety of other bar heights, bar spacings
and materials is available by special order.
2. Bearing Bar Type:
Flat Bar Grating; Serrated Bar Grating ; I Bar Grating (include
flat bearing bar and serrated bearing bar)

INSTALLATION OF STEEL GRATING:
1. There are two ways of installation for grating. One way is by
welding and other is by using installation fastener. The welding
method is suitable for those parts which will be fixed forever,such
as platforms for equipments,while the method by using installation
fastener has the properties of easy to assemble and disassemble and
of preventing destroying the zinc layer.
2. Installation fastener is suitable for all types of gratings. It
is made of up-fastener,down-fastener and inside cylinder bolt M10.
3. Welding method is angle welding at the first bearing bar of
every corners on the grating.Welding seam of which is not less than
20mm length and not less than 3mm height.
4. It at least needs four sets of installation fasteners on every
grating to fix.You had better install more fasteners on the
supportable construction when the span is larger.
5. We can supply stainless steel installation fastener to satisfy
our customer’s requirements.
6. Please indicate clearly the type,quantity and material when you
purchase installation fastener.
