About Guangdong Hehe Construction Hardware Manufacturing Co.Ltd. - Construction Hardware Supplier in China

China‑based Guangdong Hehe Construction Hardware Manufacturing Co.Ltd. lists five active products across the categories “Cupboards, Doors, Gates, Grills & Windows” and “Door Hinges”. The catalogue includes an Aluminum Sliding Folding Door System (HS 7610.10.00), an Aluminum Single Point Lock Casement Window (HS 7610.90), an Aluminum Window Friction Stay HHKS (HS 8302.41), an Upvc Sliding Window (HS 7610.10.00) and an Aluminum Window Hinge Jx42 (HS 8302.41).

The listed items use Aluminum Alloy 6063‑T5 with Zinc Alloy hardware for the sliding door system, primary Aluminum Alloy with Zinc lock hardware for the casement window, Stainless Steel 304/316 for the friction stay, Aluminum Alloy YL102 for the UPVC‑framed sliding window and an Aluminum/Zinc composite for the Jx42 hinge. All products fall under the HS‑code families 7610 (doors, windows and frames) and 8302 (base metal locks and hinges). The supplier’s product set therefore covers both structural aluminium framing and associated hardware components.

Product Range and Specialties of Guangdong Hehe Construction Hardware Manufacturing Co.Ltd.

The catalogue covers two aluminium‑based window and door systems, a stainless‑steel friction stay, a UPVC‑framed sliding window and a composite aluminium‑zinc hinge. In the wider industry aluminium alloy 6063‑T5 is the standard grade for extruded window and door profiles, conforming to ASTM B221 and EN 485, while zinc alloy hardware is commonly used for corrosion‑resistant fittings. Stainless steel 304 and 316 are the typical grades for friction stays and hinges, meeting ASTM A276 and often supplied with a surface finish of 2B or mirror polish. Buyers usually specify dimensions in millimetres, load‑bearing capacity (e.g., 150 kg m‑2 for sliding doors) and water‑tightness class according to EN 14351‑1.

Trade and Export Information - Guangdong Hehe Construction Hardware Manufacturing Co.Ltd.

China is a major exporter of aluminium door and window systems, with Europe, the Middle East, Africa and Southeast Asia representing the largest import markets. HS 7610 products are subject to customs checks for anti‑dumping duties in the EU, while HS 8302 items often require CE marking for mechanical safety. Typical buyer requirements include ISO 9001 quality management certification, CE conformity to EN 14351‑1 for windows and doors, and material certificates such as Mill Test Reports for aluminium alloys. Export shipments are usually packed in timber‑framed bundles, wrapped in protective film and loaded in 20‑ft or 40‑ft containers under FOB Shanghai or CIF destination terms.

Sourcing from Guangdong Hehe Construction Hardware Manufacturing Co.Ltd. - Buyer Guidance

When sourcing from this supplier, request Mill Test Reports for the aluminium alloy 6063‑T5 and zinc alloy hardware to verify tensile strength and chemical composition. Ask for surface‑finish samples (e.g., RAL colour charts) and performance test reports covering wind load, air infiltration and water penetration in line with EN 12792. Verify that the stainless‑steel friction stay complies with ASTM A276 and that the hinge torque meets the 0.8 - 1.2 Nm range typical for residential applications. Standard minimum order quantities are around 100 units per SKU, with a typical production lead time of 30‑45 days after sample approval; packaging is usually in timber‑frame bundles with polyethylene film protection.

What HS codes apply to the aluminium sliding folding door system?

The aluminium sliding folding door system is classified under HS code 7610.10.00, which covers aluminium doors, windows and their frames.

Which material standards are typical for the aluminium alloy used in the door system?

Aluminium alloy 6063‑T5 is commonly supplied to ASTM B221 and EN 485 specifications, providing a tensile strength of about 190 MPa and good extrudability.

What certifications should a buyer request for the stainless‑steel friction stay?

Buyers should ask for a Mill Test Report confirming compliance with ASTM A276 for stainless steel 304/316, and optionally a CE mark indicating conformity to relevant mechanical safety standards.

Is a sample available for the aluminium window hinge Jx42?

A sample of the Jx42 hinge can be requested; the supplier typically provides a single unit for dimensional and finish verification before bulk orders.

What is the typical minimum order quantity for the UPVC sliding window?

The usual MOQ for the UPVC sliding window is 100 pieces, allowing the supplier to optimise packaging in standard timber‑frame bundles.

What packaging method is used for the aluminium single point lock casement window?

The casement windows are packed in timber‑framed crates, wrapped in protective film and loaded into 20‑ft or 40‑ft containers for sea freight.

Which markets commonly import these Chinese aluminium door and window products?

European Union countries, Gulf Cooperation Council states, African nations and Southeast Asian markets are the primary import destinations for Chinese aluminium door and window systems.

What documentation should be verified before confirming an order?

Buyers should verify the Mill Test Report, CE conformity declaration, product dimensional drawings and any performance test certificates (wind load, water ingress) that match the specifications required for the target market.
