Preface: Integration of revision of this standard GB/T 706-1988 Hot-rolled beam steel--Dimensions,shape,weight and tolerances "hot rolled beams size, shape, weight and allowable deviation", GB/T 707-1988 Hot-rolled channel steel--Dimensions,shape,weight and tolerances "hot rolled steel channel size, shape, weight and allowable deviation", GB/T 9787-1988 Hot-rolled equal-leg angle steel--Dimensions,shape,weight and tolerances hot-rolled equilateral Angle steel size, shape, weight and allowable deviation ", GB/T 9788-1988 Hot-rolled unequal-leg angle steel--Dimensions,shape,weight and tolerances hot rolling unequal Angle size, shape, weight and allowable deviation ", GB/T 9946-1988 Dimensions,shape,weight and tolerances for hot-rolled L-sectional steel "hot rolled steel L size, shape, weight and allowable deviation". Instead of this standard GB/T 706-1988 Hot-rolled beam steel--Dimensions,shape,weight and tolerances "hot rolled beams size, shape, weight and allowable deviation", GB / T707-1988 "hot rolled steel channel size, shape, weight and allowable deviation", GB/T 9787-1988 Hot-rolled equal-leg angle steel--Dimensions,shape,weight and tolerances hot-rolled equilateral Angle steel size, shape, weight and allowable deviation ", GB/T9788-1988 "hot rolled unequal Angle size, shape, weight and allowable deviation", GB/T9946-1 988 "hot rolled steel L size, shape, weight and allowable deviation". This standard and GB/T 706-1988, GB/T 707-1988, GB/T 9787-1988, GB/T 9788-1988, GB/T9946-1988 compared with the main changes are as follows: - increase the normative reference files; - increases the part specifications; - adjust the size and shape allowable deviation part; - increase the technical requirements, test methods, inspection rules, packaging, logo, the provisions of the certificate of quality; - increase the appendix A. This standard annex A is normative appendix. This standard Put forward by the China iron and steel association. This standard by the national standardization technical committee under centralized steel. This standard drafting unit: maanshan iron and steel co., LTD., information standards institute of metallurgy industry, tangshan iron and steel co., LTD, laiwu steel corporation, anshan iron and steel company, shougang red smelting iron and steel company. This main draftsman of standard: Gong Qinghua, feng, li-juan wang, Deng Cuiqing, Du Chuan cure, hong-xin wang, chian, XiTie, knot to wu, xiao-ling sun, Ren Cuiying, noviceblue, Hu Nan. This standard replaced all previous releases of standard: GB/T706-1965, GB/T 706-1988 Hot-rolled beam steel--Dimensions,shape,weight and tolerances; 1 GB/T707 - 965GB/T707-1988; ---GB/T9787-1988; ---GB/T9788-1988; ---GB/T9946-1988   
Description:Integration of revision of this standard gb/t 706-1988 "hot rolled beams size, shape, weight and allowable deviation", gb/t 707-1988 "hot rolled steel channel size, shape, weight and allowable deviation", gb/t 9787-1988 the hot-rolled equilateral Angle steel size, shape, weight and allowable deviation ", gb/t 9788-1988 "hot rolled unequal Angle size, shape, weight and allowable deviation", gb / T 9946-9946 "hot rolled steel l size, shape, weight and allowable deviation".
instead of this standard gb/t 706-1988 "hot rolled beams size, shape, weight and allowable deviation", gb/t 707-1988 "hot rolled steel channel size, shape, weight and allowable deviation", gb/t 9787-1988 of the hot-rolled equilateral Angle steel size, shape, weight and allowable deviation ", gb/t 9788-9788 "hot rolled unequal Angle size, shape, weight and allowable deviation", gb/t 9946-1988 "hot rolled steel l size, shape, weight and allowable deviation".
this standard stimulates the hot rolled beams, hot rolled steel channel, hot-rolled equilateral Angle steel, hot-rolled unequal Angle and hot rolled steel l size, shape, weight and allowable deviation, technical requirements, test methods, inspection rules, package, mark and quality certificate Book.
this standard is applicable to hot-rolled equilateral Angle steel, hot-rolled unequal Angle, hot rolled steel and the inside leg l a hot rolled beams and hot-rolled channels of the slope.
this standard and gb/t 706-1988, gb/t 707-1988, gb/t 9787-1988, gb/t 9788-1988, gb/t 9946-1988 compared with the main changes are as follows:
-- Increase the normative reference file;
- increases the part specifications;
- adjusted the size and shape allowable deviation part;
- increasing technical requirements, test methods, inspection rules, packaging, logo, the provisions of the certificate of quality;
- increase the appendix a.
