Cold Rolled Steel
Cold Rolled Steel Manufacturer and Supplier in Indonesia
Cold rolled steel is manufactured by hot rolling, pickling and then cold reducing steel below its recrystallization temperature, producing sheets, strips and plates with tight dimensional tolerances, a clean smooth surface and improved mechanical properties. Sino East Steel is a cold rolled steel manufacturer and supplier based in Tianjin, China, exporting to Indonesia and more than 50 countries for over 18 years. As a direct factory supplier with a 65,000 m2 production base and 500,000 tons of annual capacity, we deliver to Indonesian importers, distributors, contractors and project companies with complete documentation, including the Mill Test Certificate (MTC) per EN 10204 3.1 on every shipment.
Indonesian buyers choose our cold rolled steel because every batch is tested in our ISO 9001:2015 certified quality system, packed seaworthy and shipped to Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), Belawan (Medan) and Makassar within 18-25 days after production. Third-party inspection by SGS, BV or TUV can be arranged at the factory or at the destination port, and SNI documentation support is available for regulated applications.
What Is Cold Rolled Steel?
Cold rolling improves thickness accuracy to +-0.02 mm or better, delivers a smooth spangle-free surface suitable for painting and forming, and increases yield strength through work hardening. Cold rolled steel is the base material for stamped automotive parts, appliance casings, office furniture, electrical enclosures, precision tubes and a wide range of consumer products.
Indonesian manufacturers and fabricators source cold rolled sheets, strips and coils from Sino East Steel for automotive component plants, appliance assembly lines, furniture factories and metalworking industries across Java and Sumatra, with stable supply and consistent batch quality.

Surface Quality and Tolerance Control
Surface quality is critical in cold rolled steel: the bright clean surface must be free from scale, scratches and roll marks so that painting, powder coating and deep drawing perform consistently. We control rolling passes, lubrication and annealing cycles to deliver the temper and surface finish specified for each application, and every coil is tested for hardness, thickness and surface condition before packing.
