Welded Bar Grating Asttm Treads 6 Welded stair treads are manufactured from standard Grating with a patterned floor plate nosing and pre-punched end plates to facilitate installation. The coating thickness shall be measured microscopically at a suitable magnification. Non-standard, cut to size expanded metal.
Below is an introduction to both specs. These weights are based on use of Welded Grating and a base tread length of 18″. Specialty or made-to-order products are often produced to an engineering drawing rather than any specification.

Next, weigh the sheet. This standard does not purport to address all of the safety concerns, if any, associated with its use.
The unique one-piece diamond shaped construction provides slip resistance asgm all directions. The distance between supporting members measured from the inside bearing point of aastm supporting member to the inside bearing point of the next supporting member.
Increased load performance has been achieved through interlocking planks and a “ventilated” rung design. Traction Tread Ladder Rungs are ideal for use in hand-over-hand ladder applications where safe footing is also required.
Expanded products typically are produced in 4-by-8 sheets, but many sizes are available. Nor does a company have to be a North American producer to meet these specifications. Measured in per sq. Dimensionally, both specs are identical. To confirm that the product delivered is what was ordered, four dimensions can be measured see graphic: Measuring standard expanded metal can be tricky even for the most experienced warehouse person armed with good calipers.
It is informational only and not an official part of the standard; the full text of the standard itself must be sstm to for its use and application. Flattened Aluminum 7 Aluminum Alloys: Any producer can manufacture product that meets either of these specifications without being a member of the Expanded Metal Manufacturers Asrm or the American Society of Testing Materials.
The values given in parentheses are for information only and may be approximate. Historical Version s – view previous versions of standard. Closed Meshed Grating is available in carbon steel, stainless Steel and Aluminum. This abstract is a brief summary of the referenced standard. Expanded metal shall be made from commercial steel, carbon steel sheets or from stainless steel sheets. Two inch cross bar centers are also offered aetm can be specified with the letter “F”- i.
Many service centers purchase and stock expanded metal sheet. Could you measure it to see if it conforms to the specification?

The deviation in inches from the original plane when the grating is placed under a load. Hot Dip Galvanized after fabrication is available upon request and special quotation. For each additional inch add the appropriate weight from table for Bearing Bar Sizes. Because of all the axtm in expanded metal, getting into the diamond becomes an exercise in patience.

Grip Strut grating is commonly used for v1267 platforms, industrial flooring, catwalks, balconies, storage areas, walkways and stair treads. Hundreds of sole-gripping dimples insure a safe surface in all kinds of environments. Heavy Duty Grip Strut is more competitive than ever against Bar Finally, the sheet size must also be specified.
The issue is that some producers may utilize thinner materials and still narrow the strand width, delivering an inferior product. Products will be offered with or without abrasive nosing. Over time, industry practice has made some of these designations less accurate. Expanded metal shall be manufactured with the corresponding thickness, design size, opening size and strand size.
Close Meshed Grating 12 Closed Meshed Grating is a pressure locked grating product, produced with close bar spacings to accommodate the requirements for pedestrian comfort and safety. Example, a pedestrian load, or light equipment load. Heavy Duty Grip Strut is a one-of-a-kind plank grating sporting a hefty 24 foot clear span capability. Flattened material has been run through a cold mill. This specification covers expanded metal.
