An Q690D steel materials, also known brands. Hydraulic supports with steel. Q: representative yield about 690, D: the impact of temperature on behalf of: -20 degrees. H?fele main road Jigang high-strength plate Q460C / D, Jigang high-strength plate Q550C / D, Jigang high-strength plate 690D / E, 360/450/500 wear plates, wear plates imported Swedish 400/450/500/550 No magnets 20Mn23AlV, Baosteel alloy plate with a large, lightweight, strength level steel hydraulic support hydraulic support gradually increased from 50kg, 60kg developed to 100kg, 110kg, 120kg and even to the level, and the level of high-strength steel The amount is growing. In order to meet market demand, the company introduced a full line of quenched and tempered heavy plate, try using no oxidation roller hearth furnace, roll quenching machine, the main product specifications for the thickness 8-120mm, width 1600-4000mm, length 4000-16000mm. Q690D has good weldability; hardened steel plate before blasting treatment, quenching furnace radiant tube heating, non-oxidizing atmosphere control and other measures to make steel with good surface quality; quenching machine dedicated roller design, zoning water cooling, etc., to ensure that steel mechanics uniform properties, and has a good plate shape. ---------------------------------------------- High-strength structural steel Q690D 3 * 1250 * 6000 Jigang WISCO, Shougang high-strength structural steel Q690D 3 * 1500 * 6000 Jigang WISCO, Shougang high-strength structural steel Q690D 4 * 1250 * 6000 Jigang WISCO, Shougang high-strength structural steel Q690D 4 * 1500 * 6000 Jigang Wuhan Iron and Steel, Shougang high-strength structural steel Q690D 5 * 1250 * 6000 Jigang WISCO, Shougang high-strength structural steel Q690D 5 * 1500 * 6000 Jigang WISCO, Shougang high-strength structural steel Q690D 6 * 1500 * 6000 Jigang WISCO, Shougang high strength structural steel Q690D 6 * 2000 * 9000 Jigang WISCO, Shougang high-strength structural steel Q690D 8 * 1500 * 6000 Jigang WISCO, Shougang high-strength structural steel Q690D 8 * 2000 * 9000 Jigang WISCO, Shougang high-strength structural steel Q690D 10 * 1800 * 9000 Wuhan Iron and Steel, Shougang Jigang high-strength structural steel Q690D 10 * 2000 * 9000 Jigang WISCO, Shougang high-strength structural steel Q690D 12 * 2200 * 9800 Jigang WISCO, Shougang high-strength structural steel Q690D 16 * 2200 * 9700 Jigang WISCO, Shougang high-strength structural steel Q690D 18 * 2200 * 10000 Jigang WISCO, Shougang high-strength structural steel Q690D 20 * 2200 * 10050 Jigang WISCO, Shougang high-strength structural steel Q690D 22 * ??2200 * 9800 Jigang WISCO, Shougang high-strength structural steel Q690D 24 * 2200 * 8700 high strength Shougang Jigang WISCO structural steel Q690D 26 * 2200 * 8000 Jigang WISCO, Shougang high-strength structural steel Q690D 30 * 2200 * 7800 Jigang WISCO, Shougang high-strength structural steel Q690D 34 * 2200 * 12000 Jigang WISCO, Shougang high-strength structural steel Q690D 38 * 2200 * 10700 Wuhan Iron and Steel, Shougang Jinan high-strength structural steel Q690D 40 * 2200 * 10500 Jigang WISCO, Shougang high-strength structural steel Q690D 42 * 2200 * 11000 Jigang WISCO, Shougang high-strength structural steel Q690D 48 * 2200 * 12000 Jigang WISCO, Shougang high-strength structural steel Q690D 50 * 2200 * 11000 Jigang WISCO, Shougang high-strength structural steel Q690D 58 * 2200 * 12000 Jigang WISCO, Shougang high-strength structural steel Q690D 60 * 2200 * 11000 Jigang WISCO, Shougang high-strength structural steel Q690D 68 * 2200 * 9800 Jigang Wuhan Iron and Steel, Shougang high-strength structural steel Q690D 70 * 2200 * 9700 Jigang WISCO, Shougang high-strength structural steel Q690D 74 * 2200 * 8600 Jigang WISCO, Shougang high-strength structural steel Q690D 82 * 2200 * 13000 Jigang WISCO, Shougang high-strength structural steel Q690D 85 * 2200 * 9600 Jigang WISCO, Shougang high-strength structural steel Q690D 90 * 2200 * 11500 Jigang WISCO, Shougang high-strength structural steel Q690D 95 * 2200 * 9900 Jigang WISCO, Shougang high-strength structural steel Q690D 100 * 2250 * 12000 Jigang WISCO, Shougang high-strength structural steel Q690D 105 * 2200 * 9600 Jigang WISCO, Shougang high-strength structural steel Q690D 120 * 2210 * 12000 Jigang WISCO Shougang quality products, reasonable price, satisfactory service is our eternal management policy.
