Material: cast iron plate by HT200-300 casting, material ingredients blend raw material content according to the following criteria (%): carbon: 3.1-3.4, MN: 0.6-0.9, SI: 1.5-2.0, 0.12, sulfur, and phosphorus 0.3. hardness > 180 second tempering.

By country Cast iron inspection platforms Latest standards GB/t 22095-2008, respectively 1, 2, 3, finish planing. Face lapping process testing using painting method, the use of skiving machining of 3 flat-face, with a surface roughness Ra of the maximum allowable value of 5um. Plane precision is guaranteed.

Civil air defense engineering material cast iron platform: HT200-250 gray alloy cast iron. Face hardness HB140---210.

Testing platform requirements: Flat face without seriously affecting the look and performance of sand, pores, cracks, inclusions, porosity, scratches, bumps, rust and other defects. Plate casting surfaces should be cleared of sand and flat, painted solid, the acute angle obtuse.

Testing platform for packaging: Wooden packaging. Anti-rust treatment prior to packaging and properly packaged to avoid damage during transport due to improper packing. With product certification, materials report and relevant national quality inspection reports.

Civil air defense engineering cast iron platform installation and load bearing: Design according to user test the maximum workpiece weight; adjust the Horn/platform support installed. Load-bearing support evenly distributed; inspection platform provides detailed installation instructions and installation drawings, including supporting arrangement plan, leveling between the Horn and the Foundation under masonry supporting design details and map. If it needs to load a larger platform, can be used by our technicians provide you with design and production.

Test platform-week examination period: Floral 2-3 months after installation, generally 612 months after
