Q195 235 SS304 316 Steel Grating for Airfield Highway Bridge Drain
Steel grid is a product, made of bearing steel bars welded to the
linking wire rod of high voltage resistance welding, which is
further processed by cutting, slotting, stiletto , trimming and
high strength, light structure with firm grids pressure welded
structure and high bearing property, easy suspending installation,
beautiful appearance ,durability with hot galvanized finish, good
anti-corrosive property, and bright surface, good ventilation,
lighting. cooling and anti-explosion. and deposit-proof.
Materials & Finishes
Pedestrian gratings are manufactured in carbon steel and 300 series
stainless steels. Carbon steel products are available bare (no
finish), painted with manufacturers standard paint, or hot dip
galvanized. Stainless steel products are available mill finish,
commercially cleaned or electro-polished.
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
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
