Our experienced project managers can effectively coordinate your multi-release schedules to make sure your job site receives the grating it needs, when it needs it.

Grating panels are piece marked and clearly identified on our supplied grating drawings to ensure accurate field installation. As we are both a manufacturer and fabricator of grating, we can offer our customers complete "One Source" solutions for all their grating needs.

From standard and heavy duty steel bar grating panels to custom fabrication, our Design Manual can help take your structural specifications to detailed drawings and on to ready-to-install grating. The twisted cross rods provide a non-slip walking surface. Vulcraft manufactures a wide variety of steel bar grating including standard, heavy duty and customized shapes and sizes with various finishes making our products suitable for all kinds of applications. Stock products can be supplied quickly from strategically located sales and warehouse facilities.

Also, custom grating jobs can be manufactured to very particular requirements by our personnel in either Imperial or Metric measurements. They also are used extensively in the transportation industry, including railroad, airport and transport truck, and in the military.

Standard Duty steel bar grating is the most popular grating product manufactured by Vulcraft. Nearly all sizes in Standard Mesh Type Type metric are readily available in our warehouses or stocked on the shelves of our distributors. Simplicity in design is surpassed only by its versatility in usage. Heavy Duty steel bar grating has the strength for substantially heavy load areas such as airfields, industrial plants, truck and bus terminals, parking lots and railroad yards.

Common uses are flooring, driveways, subway and tunnel ventilation grilles, curb inlet grates, ramps, docks, etc. High temperatures, combined with high pressure, fuse the bearing bars and cross bars together to form a permanent joint.

Welded steel stair treads are the most widely used for their strength and ease of installation and are universally used in most industrial and commercial applications. Both can be ordered with a serrated surface for additional safety. Rectangular bar stair treads provide a high strength and stiffness-to-weight ratio and are available with a serrated surface when additional safety is required.

Invoicing area or net area for grating ordered to specific dimensions without drawings will be based on length by width of each panel, with no deductions for cutouts. For grating supplied from a drawing, the invoicing area shall be on the basis of gross floor area measured out to out of grating, with no deductions for clearances. The Seller shall not be responsible for the actual dimensions of construction work in the field, but shall be responsible for the accurate fabrication of grating and treads in accordance with plans and specifications, if applicable.

Heavy Duty vehicular grates are illustrated on page 15 of this catalog. Inlets may be specified to any clear opening by simply indicating the desired "W" width and "S" span dimensions illustrated on page Similar to our trench grating systems, any of the five embed frame profiles may be specified to meet the exact needs of your application.

While all gratings are manufactured with plain walking surface, the optional serrated surface may be specified. The ends of all inlet gratings are trench banded to enhance durability and allow for maximum drainage. Unless otherwise specified, all inlet grates and frames are hot dip galvanized in accordance with ASTM specification A All grating must be firmly fastened in place.

Welding panels to the supporting structure provides a superior, permanent installation. Gratings subject to removal can be fastened with Weld Lugs which are shop welded between the bearing bars, or anchored with Saddle Clips. In areas where welding or drilling is not permitted, "G" Clips can provide the fastening solution.

These clips install on the top surface of the grating and create a friction connection with the flange supporting the panel. The narrow spacing of close mesh gratings allows for countersinking of the bearing bars and fastening with flat head screws. Grating panels are manufactured in nominal 24" and 36" standard widths.

When considering alternative widths, consult the table below to select widths that will maintain consistent out to out spacing of the bearing bars. Widths specified which deviate from the table below can be fabricated utilizing side banding. In so doing, the outside bearing bar spacing on one side of the finished panel will deviate from the spacing throughout the rest of the panel.

As stated above, stock grating panels are manufactured in 24" and 36" nominal widths. Stock lengths span are 24'-0" for all sizes with most popular bearing bar sizes also available in 20'-0" lengths. These sizes allow for efficient layout and waste minimization when they are fabricated to your exact specification.

Unlike many competing products, individual grating panels do not require supports on all four sides of each cut piece. Bar grating panels only require support perpendicular to the bearing bar span. There is no need to place supports parallel to the bearing bars where adjacent panels are installed in succession. The following layouts illustrate proper layout and support of a simple bar grating platform.
