=== 膨胀金属格栅（由碳钢制成大部分）由以常规形式膨胀的金属板制成，然后经过冷轧减径机。在这个过程中，片材的长度被拉长——通常约为5%——但片材的宽度保持不变。然后将板材送过整平机以保持其平整度。
膨胀金属钢格栅的一般信息：
孔：菱形、方形
图案：标准-凸面
特点：优雅，抗压强度，耐用，防锈，刚性
通用规范：
格栅板（长距离）尺寸：4.5---100mm
短路尺寸：2.5---50mm
钢绞线厚度：最大8.0mm
钢绞线宽度：最大至8.0mm
使用扩展钢格栅的好处：
&公牛；膨胀金属允许光、热、声音和空气自由流动
&公牛；穿孔金属的经济有效替代品。你不需要为这些洞买单；在膨胀过程中没有浪费
&公牛；与编织线不同，金属格栅在切割时不会散开
•Available in a variety of mesh configurations including diamond, square, round, hexagonal plus architectural and decorative patterns
•Expanded metal is a formidable barrier when used in security applications
•Easily fabricated, finished, installed and formed
Application: Expanded steel grate panels are mainly applied as platforms and walking stair treads for constructions, vessels, bridges and boilers and also be used as reinforcement for light construction materials and concrete pouring, radiator grills on all types of vehicles and air compressors, safety guards for gear-drive equipment on various kinds of machines.

Expanded metal grating is the most practical and economical way to assure strength, safety, and a non-skid surface. Expanded metal grating is ideal for use on plant runways, working platforms, and catwalks, as it is easily cut into irregular shapes and can be installed quickly by welding or bolting.
Classification of Expanded metal Steel Grating according to opening:
Variety: small, medium and heavy expanded metal. Opening in the shape of diamond, hexagonal or special shape.
