About Guangzhou Intone Audio Co., Ltd. - Stainless Steel Coils Supplier in China

Guangzhou Intone Audio Co., Ltd. is based in China and currently lists five distinct steel products in its catalogue. The offerings cover hot‑rolled (HR) coils classified under HS code 7208.39 made from carbon steel SS400, HR strips under HS code 7211.13 of carbon steel grades Q195, Q215 and Q235, stainless‑steel wire rod under HS code 7223.00 with material SS 304 (18 % Cr, 8 % Ni), deformed bars under HS code 7228.50 of stainless steel 304/316, and a generic line of angles without a specific HS code listed.

The product set aligns with the supplier’s top categories, which include Stainless Steel Coils, Steel Strips, Stainless Steel Rods & Strips, Stainless Steel Bars and Frames. Each entry references the material grade and HS‑code family, providing a clear view of the steel grades and forms that Guangzhou Intone Audio makes available for export.

Product Range and Specialties of Guangzhou Intone Audio Co., Ltd.

The catalogue lists HR coils (7208.39) of carbon steel SS400, HR strips (7211.13) of Q195‑Q235 carbon steel, stainless‑steel wire rod (7223.00) of AISI 304, deformed bars (7228.50) of stainless‑steel 304/316, and angles with no HS‑code disclosed. These items are typical hot‑rolled or cold‑formed structural steel products used in construction, machinery, and fabrication.

In the broader steel market, HR coils are usually supplied in widths from 500 mm to 2000 mm with thicknesses between 1 mm and 20 mm and conform to ASTM A1011 or EN 10305. HR strips commonly appear in thicknesses 0.5‑12 mm and are graded to ASTM A36 or EN 10025. Stainless‑steel wire rod is frequently produced in diameters 5‑50 mm and meets ASTM A108 or ISO 4957 for SS 304. Deformed bars for reinforcement follow ASTM A615 (Grade 60) or EN 13934, while angles are standard structural sections meeting ASTM A36 or EN 10034. Buyers can therefore expect material certifications, dimensional tolerances, and mechanical properties that align with these standards.

Trade and Export Information - Guangzhou Intone Audio Co., Ltd.

China remains one of the world’s largest exporters of carbon and stainless steel products, with HS chapters 72 covering most of the listed items. Major import regions for these steel forms include Southeast Asia, the Middle East, Europe and North America, where the materials are used in building, automotive, shipbuilding and heavy equipment sectors. Buyers typically require ISO 9001 quality‑management certification, mill test certificates (MTC), and compliance with ASTM or EN standards; many importers also request CE marking for products destined for the EU market.

Logistically, the products are normally shipped in 20‑ft or 40‑ft containers on wooden pallets or bundled on steel straps, using FOB or CIF incoterms. Chinese exporters often provide phytosanitary or anti‑contamination statements for steel, and customs authorities may apply anti‑dumping duties on certain HS codes (e.g., 7208, 7211). The supplier’s target markets are not specified, so typical buyers are manufacturers and distributors in the aforementioned regions who handle structural and reinforcement steel.

Sourcing from Guangzhou Intone Audio Co., Ltd. - Buyer Guidance

When sourcing from Guangzhou Intone Audio Co., Ltd., request the mill test certificate for each steel grade to verify chemical composition, tensile strength and hardness. Verify that the HR coils and strips meet the dimensional tolerances of ASTM A1011/A36 and that the stainless‑steel rod and deformed bars conform to ASTM A108 or A615 specifications, including corrosion‑resistance data for SS 304/316.

Confirm packaging details such as bundle size, pallet dimensions and whether the angles will be supplied with protective coating. Minimum order quantities for bulk steel are commonly set at one metric ton, with lead times ranging from 30 to 45 days after receipt of a confirmed purchase order and required test documentation.

What material grades are offered for the hot‑rolled coils?

The hot‑rolled coils are made from carbon steel SS400, which corresponds to the standard grade used in ASTM A1011 and EN 10305 for structural applications.

Which HS code applies to the stainless‑steel wire rod?

The stainless‑steel wire rod is listed under HS code 7223.00 and is produced from AISI 304 stainless steel (18 % Cr, 8 % Ni).

Are mill test certificates available for the deformed bars?

Buyers should request a mill test certificate that confirms the stainless‑steel 304/316 composition and mechanical properties in accordance with ASTM A615 or EN 13934.

What are the typical dimensions for the hot‑rolled strips?

HR strips are commonly supplied in thicknesses from 0.5 mm to 12 mm and widths up to 1500 mm, meeting the tolerances of ASTM A36 or EN 10025.

How are the angles packaged for export?

Angles are usually bundled and strapped on wooden pallets, ready for loading in standard 20‑ft or 40‑ft containers; buyers should confirm any coating or rust‑preventive treatment required.

What certifications should a buyer verify before ordering?

Buyers should verify ISO 9001 quality‑management certification, request mill test certificates, and ensure compliance with the relevant ASTM or EN standards for each steel grade.

What incoterms are commonly used for these steel products?

FOB (Free on Board) and CIF (Cost, Insurance, Freight) are the typical incoterms used for steel exports from China.

What is the usual lead time for a first order?

Lead times are generally 30‑45 days after the purchase order is confirmed and all required test reports and documentation are received.
