About Yonggu Hardware Products Co., Ltd. - Aluminum Supplier in China

Yonggu Hardware Products Co., Ltd. is based in China and currently lists eleven active products in its catalogue. The company focuses on aluminum‑based hardware such as boxes, enclosures, chassis and extrusion cases, covering the HS‑code families 7610.90 for general aluminum articles and 7616.99 for extruded aluminum products. Each listed item is described with its material composition, predominantly aluminium alloys 6063 and 5052, which are standard for lightweight yet robust structural components. The catalogue includes items ranging from a 19‑inch rack‑mount chassis to specialised boxes for printed‑circuit‑boards and audio amplifiers, reflecting a narrow but clearly defined product set.

The product list contains items such as an Aluminum Box for PCB, Hard Drive Enclosure, Aluminum Box for Instrument, Aluminium Tool Boxes, Electrical Enclosures, Extruded Aluminium, Aluminium Project Box, 19‑Inch Rack Mount Chassis, Aluminium Power Amplifier Chassis (HS 7610.90, alloy 6063 + 5052), Aluminium Storage Box and a 1 U Aluminium Extrusion Case (HS 7616.99, alloy 6063 + 5052, anodised). All products are fabricated from aluminium alloy profiles that meet common aerospace and electronics enclosure standards, and the HS codes indicate they fall under the broader categories of finished aluminium articles and extruded sections for industrial use.

Product Range and Specialties of Yonggu Hardware Products Co., Ltd.

The catalogue’s eleven items are all aluminium enclosures or chassis, each built from alloy 6063 (often supplied in T5 temper for good formability) or alloy 5052 (preferred for its corrosion resistance). In the industry, aluminium enclosures of this type are typically supplied to meet IEC 60529 IP ratings ranging from IP20 for indoor equipment to IP54 for dust‑protected environments, and they may carry UL‑94 V‑0 flame‑retardant certification when required for electronic housings. Standard dimensions for rack‑mount chassis follow the 19‑inch EIA‑310 standard, while project boxes and storage boxes are offered in modular lengths and depths that align with common PCB sizes such as 100 mm × 100 mm or 200 mm × 200 mm. Anodised finishes on the 1 U extrusion case are usually measured in microns (e.g., 10 µm) to provide a uniform surface and additional corrosion protection.

Trade and Export Information - Yonggu Hardware Products Co., Ltd.

China remains one of the world’s largest exporters of aluminium extrusion and fabricated aluminium products, with the majority of shipments directed to electronics manufacturers in Southeast Asia, Europe and North America. HS 7610.90 covers “other aluminium articles” such as chassis and enclosures, while HS 7616.99 is used for “other extruded aluminium products” that do not fall under more specific headings. Importers typically request ISO 9001 quality‑management certification, RoHS compliance for restricted substances, and where applicable CE marking for equipment enclosures. Logistics for aluminium hardware usually involve 20‑ft or 40‑ft containers, packed in double‑wall corrugated boxes or wooden crates, and common Incoterms are FOB Shanghai or CIF Los Angeles, depending on the buyer’s preference.

Sourcing from Yonggu Hardware Products Co., Ltd. - Buyer Guidance

Buyers should obtain a material test report confirming the exact alloy composition (e.g., Al 6063 T5, Al 5052 H32) and mechanical properties such as tensile strength (≈ 200 MPa for 6063) and yield strength (≈ 150 MPa). Request documentation on surface treatment - anodising thickness, colour, and any powder‑coat coating - as well as the IP rating and any applicable flame‑retardant certification. It is advisable to ask for a pre‑production sample to verify dimensions, mounting hole placement and finish before confirming larger volumes; typical minimum order quantities for custom aluminium boxes range from 100 to 500 units, with lead times of 30‑45 days after design approval.

What aluminium alloys are used in the Power Amplifier Chassis and the 1 U Extrusion Case?

Both items are fabricated from a blend of aluminium alloy 6063 and alloy 5052. Alloy 6063 provides good extrudability and surface finish, while 5052 adds corrosion resistance, especially for anodised finishes.

Which HS codes apply to the aluminium enclosures listed in the catalogue?

The Aluminium Power Amplifier Chassis is classified under HS 7610.90, covering other aluminium articles. The 1 U Aluminium Extrusion Case falls under HS 7616.99, which is used for other extruded aluminium products.

What certifications should a buyer request for these aluminium hardware products?

Buyers should request ISO 9001 quality‑management certification, RoHS compliance documentation, and, where the enclosure will be used in regulated markets, CE Declaration of Conformity or UL fire‑rating certificates.

What typical dimensions and standards apply to the 19‑inch Rack Mount Chassis?

The chassis follows the EIA‑310 19‑inch rack standard, with a width of 19 inches (482.6 mm) and a depth that commonly ranges from 300 mm to 600 mm. It is designed to accommodate standard 1‑U to 4‑U equipment modules.

Are there standard IP ratings for the Electrical Enclosures and Storage Boxes?

Electrical enclosures are frequently supplied with IP20 for indoor use or IP54 for dust‑protected environments. Storage boxes intended for outdoor or harsh environments may be offered up to IP65, depending on the buyer’s specification.

What packaging and shipping methods are typical for these aluminium products?

Products are usually packed in double‑wall corrugated cartons with internal cushioning, then placed in standard 20‑ft or 40‑ft containers. Shipping terms often use FOB Shanghai or CIF destination port, with the choice depending on the buyer’s logistics preferences.

How can a buyer obtain a sample before placing a larger order?

The supplier can provide a pre‑production sample after receiving detailed drawings and specifications. Sample lead times are generally 10‑15 days, allowing the buyer to verify dimensions, finish and fit before confirming volume production.

What are common minimum order quantities and lead times for custom aluminium boxes?

Typical MOQs range from 100 to 500 units, depending on the complexity of the design and surface treatment. After design approval, production lead time is usually 30‑45 days.
