Steel Sheets
Steel Sheets Manufacturer and Supplier in Indonesia
Steel sheets and plates are flat-rolled steel products in hot rolled, cold rolled and coated finishes, used across construction, fabrication, shipbuilding and manufacturing. Sino East Steel is a steel sheets 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 steel sheets 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 Steel Sheets?
Steel sheets and plates are the workhorse material of fabrication: hot rolled plates and sheets for structural work, pressure vessels and shipbuilding; cold rolled sheets for precision forming and painting; and galvanized sheets for corrosion-resistant cladding and ducting. Thickness ranges from 0.5 mm sheet to 60 mm plate, supplied to ASTM A36, A572, A653 and EN 10025 specifications.
Indonesian fabricators, steel service centers and manufacturers buy steel sheets and plates from Sino East Steel in standard sizes, cut-to-size blanks and coils, with full MTC documentation and stable supply for project and production programs.

Flatness, Thickness Tolerance and Cutting
Flat-rolled quality is defined by thickness tolerance, flatness, surface condition and edge quality.

For structural plates we verify mechanical properties per heat, and for galvanized sheets we verify coating weight per batch.
