Flattened Expanded Metal

描述

Flattened expanded metal is manufactured by passing the metal through a cold roll reducing mill parallel to the LWD. It is Standard Expanded Metal that has been rolled through a flattening machine in the expanding process. By flattening the sheet, the bonds and strands are turned down to produce a smooth and flat surface – essentially elongating the LWD of the diamond. Flattened Expanded Metal with versatile and be bent or formed in any direction is used in billboard walkways, catwalks, stairs, drying racks, vents, ramps, walkways, flooring.

Materials: stainless steel, carbon steel, brass, aluminum, nickel, Al-Mg alloy.

Flattened Expanded Metal Features:

• Lightweight.
• Economical.
• Versatile.
• Low Maintenance.
• Can be bent or formed in any direction.
• U-edging for finished edges.

Flattened sheets:

1. Camber—The greatest deviation of a side of edge from a straight line after flattening shall not exceed 3/32 inch per foot (0.8 mm per 100 mm) of dimension.
2. Thickness—shall not be less than 70% of the nominal thickness specified for the sheet from the item produced.
3. Squareness—Ends shall not be more than 1/8 inch per foot (1 mm per 100 mm) out of square or 1/2 inch (12.7 mm) overall.
4. Flatness (Levelness)—Sheets shall be free from waves or buckles that are in excess of 1-1/2 inch (38.1 mm) from a plane surface.

Application:

Flattened expanded metal is widely used as panels, screens, railings, security partitions, reinforcement, gratings, window guards, anti-dazzle screens, fencing, grilles and in billboard walkways, catwalks, stairs, drying racks, vents, ramps, walkways, flooring.
