MIL-M-17194D, MILITARY SPECIFICATION: METAL, EXPANDED, STEEL (01 AUG 1986) [S/S BY ASTM-F1267]

Contact Ff1267 Statement Terms of Use. What You Need to Know. Search Back Issues Expanded Standard: Could you measure it to see if it conforms to the specification? Do you even know there is a specification? Many service centers purchase and stock expanded metal sheet. Below is an introduction to both specs. To identify f167 product, it helps to be familiar with some basic nomenclature.

Ff1267 time, industry practice has made some asrm these designations less accurate. Raised material, with its multiple facets, is what comes out of the expanding press.

Flattened material has been run through a cold mill. Standard material is often used for its traction, in a ladder or catwalk for example, while flattened material might be used for a grilling surface. Finally, the sheet size must also be specified. Expanded products typically are produced in 4-by-8 sheets, but many sizes are available. Sheets also can be sheared to produce custom sizes. To confirm that the product delivered is what was ordered, four dimensions can be measured see graphic: This is perfectly allowable since there is variation within gauges of base metals.

As thicker material is used to produce a given product, the strand width can be reduced to compensate, thereby keeping the weight per square foot the same. The issue is that some producers may utilize thinner materials and still narrow the strand width, delivering an inferior product. To protect themselves, buyers should take the following steps. Next, weigh the sheet.

Standard weights are published per square feet. If the sheet delivered weighs less than On grating products, which are typically load bearing, the allowed variation is limited sstm plus or minus 5 percent. Specialty or made-to-order products are often produced to an engineering drawing rather than any specification.

These are generally designed for a specific purpose and might be produced to meet some other, more important criteria, such as fitting into a jig. Manufacturers of shopping carts, lockers or aastm often have their own internal requirements for expanded metal. They may legitimately differ from the normal, pattern-sized sheets generally stocked and sold by metal service centers.

Measuring standard expanded metal can be tricky even for the most experienced warehouse person armed with good calipers. Because of all awtm angles in expanded metal, getting into the diamond becomes an exercise in patience.

To measure the strand thickness, the calipers must be flat g1267 the thickness of the bond. Standard or raised expanded metal should not be reduced in thickness from the base metal from which it was made.

There are very few differences between the two expanded metal specifications.

Dimensionally, both specs are identical. Any producer can manufacture product that meets either of these specifications without being a member of the Expanded Metal Satm Association or the American Society of Testing Materials. Nor does a company have to be a North American producer to meet these specifications.

To protect themselves from receiving inferior products, service centers would be well advised to source expanded metal from suppliers, both domestic and foreign, that adhere to these standards. EMMA is available on-line and can be downloaded at www.
