I mainly sell Tianjin channel steel, cold galvanized channel steel Wuqing. National Sales Hotline :18622303953,022 59,695,052 QQ: 306 090 003 company to provide long-term supply channel steel, cold galvanized channel Wuqing], low price, quality of service, if you are on our supply channel of cold galvanizing channel the Wuqing] interested, please feel free to contact me, thank you! ! The hot galvanized channel also called hot dip galvanized channel steel and hot-dip galvanized channel, is an effective anti-corrosion of the metal, mainly used in the metal structure of the industry facilities. The rust steel hot galvanized channel immersed in liquid zinc melt around 440 ~ 460 ℃, steel members attached to the surface of the zinc layer, which play the purpose of the anti-corrosion. Channel were common channel steel and light channel steel. Light channel is the actual weight of the theoretical weight lighter, geometric smaller size such as 10 # tank. Common sizes are 100 * 48 * 5.5 wt 10KG / m. The size of the light is 100 * 46 * 4.5, and the weight of 8.59KG / m. Material Q235. Light channel steel channel steel, is the actual weight of the theoretical weight lighter, smaller geometric dimensions (the same height and other dimensions than the ordinary channel thin). Specifically such as: the channel specifications with a height (h), Leg Wide (b), the waist thickness (d) dimensions expressed. Domestic channel specifications from 5-40, height of 5-40cm. The same height, the light channel is narrower than the channel steel legs, waist thin, light weight. The raw billet production channel for the carbon content of not more than 0.25% carbon structural steel or low alloy steel billets. The channel is a universal section steel material, widely useful. Mainly used in steel structure aspects, such as bridges, steel racks do beams, columns, braces (pole) and so the main features in one direction Flexural Performance is good, but weak in another direction. If the the two channel steel buckle parties welding, alternative side tube for use in structural welding use two channel back-to-back alternative to the I-beam or H-beam.
