Ltz Window Sections are precision‑manufactured ERW steel profiles intended for window and door frame construction. They are offered in the standard size designations LTZ28, LTZ29, LTZ34 and LTZ38, with wall thickness ranging from 0.4 mm to 1.5 mm. The sections are produced from carbon‑steel grades Q235 and Q195 and conform to ASTM A53‑2007 and GB/T 13793‑1992 specifications. Lengths are supplied between 4 m and 12 m, matching typical project requirements.
Q235 and Q195 steels provide a tensile strength around 400 MPa, which is typical for structural window framing. The electric‑resistance‑welded (ERW) process yields tight dimensional tolerances, usually ±0.5 mm, a standard for precision‑welded profiles. Suppliers often apply a hot‑dip galvanised coating as a typical corrosion‑protective finish for fenestration components. The sections’ weight is approximately 7 kg per metre for a 0.8 mm wall, a typical figure used in logistics calculations.
These sections are purchased by window manufacturers, façade contractors and building‑material distributors for residential and commercial projects. Hebei Sinostar Trading Co., Ltd. can ship the profiles internationally, but buyers should confirm the minimum order quantity and exact delivery schedule with the supplier. Importers are advised to verify the agreed Incoterm, request a mill test report and arrange third‑party inspection before loading.

Hebei Sinostar Trading Co., Ltd. is headquartered at No. 118 Zhongshan East Road, Shijiazhuang, Hebei, China. The company holds a harbour‑level trust tier, indicating it has passed the marketplace’s basic verification checks. Its recorded response rate is currently 0 %, meaning no replies have been logged in the platform’s system. Sinostar lists a broad catalogue that includes pre‑galvanised, hot‑dipped, electrical‑metallic tubing, black steel and embossed pipes.
A dedicated quality‑control department is mentioned, staffed by trained professionals who oversee product conformity. For the Ltz window sections, the factory follows the ASTM and GB/T standards cited in the product data. The supplier does not publish specific certifications or production capacities, so buyers should request any required test reports directly. Communication channels are limited, so confirming contact details before negotiation is advisable.
Ltz window sections are precision-manufactured ERW steel profiles designed for window and door frame fabrication, available in sizes LTZ28 through LTZ38 with wall thickness from 0.4 to 1.5mm. Made from Q235 and Q195 carbon steel to ASTM A53 and GB/T 13793 standards, these sections offer excellent weldability and structural integrity for fenestration applications. Supplied in 4-12m lengths, they are a core component for window manufacturers and construction projects sourcing internationally.

Before placing an order, importers should verify that Hebei Sinostar Trading Co., Ltd. is a legally registered entity in China and that its harbour‑level trust tier matches internal risk criteria. Request copies of the business licence, tax registration and any applicable quality certificates such as ISO 9001. Because the platform shows a 0 % response rate, confirm a reliable point‑of‑contact and obtain written confirmation of product specifications.
Shipping arrangements should be clarified early, including the preferred Incoterm such as FOB Tianjin or CIF Shanghai, as the supplier does not list a default term. Buyers need to ask for an estimated production lead time and whether the company can cut the 4‑12 m sections to the lengths required for their projects. Payment methods commonly accepted are L/C and T/T, but the exact terms must be negotiated directly with the supplier.
Importers are advised to arrange a third‑party inspection either at the factory or before loading, focusing on weld quality, dimensional accuracy and coating integrity. Request a mill test report and, if a galvanised finish is used, a zinc coating thickness certificate. All relevant documentation - including the commercial invoice, packing list, bill of lading and certificate of origin - should be verified against the purchase order to avoid customs delays.
