Dovetail Pressure Locked Grating is assembled by inserting pre-punched bearing and cross bars into an interlocking configuration and deforming the cross bars under intense hydraulic pressure. Dovetail Pressure Locked Grating is ideal for many architectural and ornamental applications.
Dovetail Pressure Locked Grating is available in type “DT” Dovetail Pressure Locked Steel Grating, type “DTS” Dovetail Pressure Locked Stainless Steel Grating, or type “ADT” Dovetail Pressure Locked Aluminum Grating.
Type “DT” steel gratings have rectangular cross bars that are slotted to fit into pre-punched bearing bars which are assembled and permanently connected under intense hydraulic pressure. In addition to being one of the most aesthetically appealing floor gratings with its clean uniform lines, the interlocking design provides excellent lateral stability and axial load distribution. The multiple combinations of bearing bar / cross bar sizes and spacing on type “DT” gratings make them popular for architectural applications such as sun shades, fencing and infill panels with a deeper cross bar serving as a distinct architectural accent.
Type “DT” gratings are available in close mesh ADA conforming spacings. Type 7-DT-4 with 3/16″ thick bearing bars provides a net 1/4″ clear opening between the bearing bars. This narrow opening is often preferred in public areas where concerns of drainage and the presence of high heeled shoes converge.

Products left unfinished will display discoloration from welding, cutting and grinding. Satisfactory for industrial or process applications where appearance is not a consideration.
Hot dip galvanized in accordance with ASTM A-123. Galvanized finish is used to resist rust.
IG GRITWELD™ utilizes processes developed for thermal sprayed hard surfacing and incorporates anti-skid ingredients to the super hard substrate. IG GRITWELD™ offers the ultimate in traction and longevity for extreme environments.
IG ECOCOAT™ is an economic and eco-friendly solution. It is dipped in one shop coat of our specially produced gloss black paint providing a protectant cover.
Stainless Steel products typically require secondary cleaning. IG ECOCLEAN™ provides a uniform and clean finish by abrasive blasting followed by passivation to remove manufacturing contaminants.
Bent clips bridging two bearing bars, available in galvanized steel, stainless steel or aluminum. Standard bolt holes are 5/16″.
Mechanical fasteners that are installed on the top surface of the grating and create a friction connection with the flange supporting the panel. “G” clips are easily installed without drilling or welding.
Plates punched with holes and shop welded between the bearing bars to facilitate bolting to the supporting structure. Bolts, screws or other connecting hardware shall be supplied by others.
To be used with narrow spacing of close mesh gratings that require a solid fastener. Counter bore allows for the use of self-drilling fasteners which are recessed below the top surface.
