Product Description: 1, Gate Scaffolding main mast pole selection φ42.7 × 2.3 steel production. 2, gantry scaffolding gantry design scientific, standardized structure size, gantry scaffolding single door frame lighter, no need to fight demolition tools, more convenient and fast. 3, Gate Scaffolding good overall framework of reliability, load capacity, high construction efficiency. 4, HT-type gantry steel scaffolding widely used in construction and for a variety of projects meters advertising industry, decoration industry, companies large equipment installation, maintenance stents. Products with acid hydrolysis, high strength, high flexibility, high abrasion resistance, excellent antistatic properties. The method of producing polyurethane casting systems, polyurethane products are made by pouring liquid polyurethane casting by means of a method of manufacturing the product, which is compared with the conventional rubber roller, having a high mechanical strength (2 to 3 times the natural rubber) ; excellent abrasion resistance (natural rubber 5 to 10 times); oil resistance, solvent resistance, superior resistance to oxygen, ozone resistance, outstanding performance, smooth surface, smooth, delicate, appearance and color uniformity, wide range of hardness and high hardness Under still has high elasticity (which is not found in other types of plastic characteristics); excellent machining properties;-metal bond strength is much higher than other rubbers.
