轻钢龙骨挂瓦条

轻钢龙骨介绍： 轻钢龙骨是以连续热镀锌板带为原材料，经冷弯工艺轧制而成的建筑用金属骨架。外观质量轻钢龙骨外形要平整，棱角清晰，切口不允许有影响使用的毛刺和变形。镀锌层不许有起皮、起瘤、脱落等缺陷。外观质量检查时，应在距产品0.5m处光照明亮的条件下，进行目测检查。轻钢龙骨表面应镀锌防锈，其双面镀锌量：优等品不小于120g/m*m。 Light steel keel is a kind of metal framework for construction, which is made of high-quality continuous hot-dip galvanized sheet and rolled by cold bending process. Appearance quality: the light steel keel shall be smooth in shape, with clear edges and corners, and no burr or deformation affecting the use of the cut is allowed. The zinc coating shall be free of defects such as peeling, nodulation and falling off. During appearance quality inspection, visual inspection shall be carried out under the condition of bright light at 0.5m away from the product. The surface of light steel keel shall be galvanized and rustproof, and the amount of double-sided galvanizing shall be no less than 120g / m * m for superior products. 轻钢龙骨质量好坏决定性因素： 1、钢带； 2、轻钢龙骨成型设备； 3、轻钢龙骨钢带的厚度偏差大小； 4、轻钢龙骨双面镀锌量； 5、外观质量； 6、龙骨厂家的精细管理。 The decisive factors of light steel keel quality are as follows: 1. High quality steel strip with high quality; 2. Light steel keel forming equipment; 3. Thickness deviation of light steel keel and steel strip; 4. Galvanized quantity on both sides of light steel keel; 5. Appearance quality; 6. Fine management of keel manufacturers.
