Process hot galvanized angle: angle pickling → washing → → drying solvent dip fluxing rack preheat → → cooling → passivation → washing → polishing → HDG completed. Hot galvanized angle galvanized layer thickness uniformity, up 30-50um angle, reliability, between the zinc coating and the steel is metallurgically bonded, become a part of the steel surface, so hot galvanized angle coating durability more reliable. Equilateral angle when calculating the theoretical weight density steel is 7.87g / m3 according to the agreement. Equilateral angle steel weight per meter tolerance must not exceed + 3% and 5% dimensional inspection methods to check the outer corner of the side end and angle passivation model and measuring rod. can not make the diameter of the rod when the measurement is equal to 0.18d through the passivation site. Check equilateral angle length with a ruler or tape measure most of the major construction steel varieties have price adjustment, the price of flat plate bid. Intraday price varieties are HPB235Φ6.5mm high line, HRB335Φ20mm HRB400Φ8-10mm plate, screw steel and galvanized angle number one tons, the majority of which HRB335Φ20mm steel rebar price. Look plate wholesale aspect angle, 15 have two mills plate and hot rolled coil were price adjustment, the price fell. Days of heavy steel mills in east China and the southwestern region of sunshine it's SS4004.75mm general volumes were down by 30 yuan / ton and 280 yuan / ton; and heavy steel prices also Q23520mm its subsidiary P Plate down 200 yuan / ton yesterday, the largest decline in steel.
