Ordinary beam and light beam of the wing to the edge of the root cause of the gradual thinning of the I-beam channel, there is a certain point of view, the ordinary beam and light beam model with its waist-high cm number of Arab numerals and different web and flange thickness and flange width specifications to waist high (h) × leg width (b) × waist thick (d) of the coin number, such as "general workers 160 × 88 × 6" groove Steel beams, it means that the high waist of 160 mm, leg width of 88 mm I-beam, I-beam waist thick as an ordinary 6 mm. Steel water gate is hydroelectric power stations and reservoirs to control water main steel structure, it will be part of long-term immersion in water, surface erosion by microorganisms (such as adsorption nail scorpion, which is acidic excrement). Another part of long-term exposure to the atmosphere, especially mine waterline beam, surfing and water impact on floating objects, but also by the high tide, the impact of low tide, so this part of the steel surface regularly alternating wet and dry, particularly vulnerable to rust. Now using wire spray zinc, aluminum spray process, greatly improve the corrosion resistance of the steel gate, anti-corrosion life than the original paint process employed increased by 5 to 6 times.
