About Foshan City Kingsun Electrical Co., Ltd. - Electric Panels & Switch Boards Supplier in China

China hosts 78 active product listings from Foshan City Kingsun Electrical Co., Ltd. The catalogue spans eight top categories, including Electric Panels & Switch Boards, Electric Conduits, Flanges, Electric Components, Metal Products, Adaptors, Temperature Controllers & Indicators, and Electric Circuit Breakers. Within the electrical enclosure segment the supplier lists metal and PVC back boxes, knock‑out boxes, pattress boxes and various gang configurations such as 1 Gang, 2 Gang, 3 Gang and 4 Gang models. Two items - a 1 Gang Galvanized Metal Electrical Box and a 2 Gang Metal Knock Out Box - are recorded with HS code 8538.90 and specify hot‑dip galvanized steel and galvanized steel as materials. The remaining items are described without HS codes but fall under the same HS‑8 chapter for electrical apparatus for switching or protecting. The product titles indicate metal back boxes, iron boxes, shallow boxes and PVC octagon boxes, reflecting a focus on wiring and outlet enclosure solutions.

The supplier’s list includes both single‑gang and double‑gang metal back boxes, PVC pattress boxes for surface mounting, and deeper iron boxes for heavier loads. Several entries mention “knock‑out” designs that allow field‑cut openings for conduit entry. Materials range from hot‑dip galvanized steel (SGCC) to standard PVC, providing options for corrosion‑resistant industrial use and lightweight residential installation. The presence of both metal and PVC formats aligns with typical market segmentation where metal enclosures serve commercial or industrial wiring, while PVC enclosures are common in domestic projects.

Product Range and Specialties of Foshan City Kingsun Electrical Co., Ltd.

The current catalogue offers a variety of enclosure types: 1 Gang and 2 Gang metal back boxes, single and double gang PVC pattress boxes, knock‑out boxes, shallow and deep boxes, as well as iron boxes for high‑current applications. In the electrical enclosure market, metal boxes are usually fabricated from hot‑dip galvanized steel to meet IEC 60529 IP‑rating requirements and to provide mechanical strength of at least 1 MPa tensile stress. PVC boxes commonly comply with UL94 V‑0 flame‑retardant classification and are sized to accommodate standard European and North American conduit diameters (e.g., 20 mm, 25 mm). Typical industry grades include IEC 60947‑1 for metal enclosures and IEC 60335‑1 for residential PVC housings. Buyers often request dimensions (width × height × depth in mm), mounting depth, and load‑bearing capacity, which for 2 Gang metal boxes can reach 15 kg and for PVC boxes around 5 kg.

Chinese manufacturers of electrical boxes frequently certify compliance with CE marking, RoHS restriction of hazardous substances and may hold ISO 9001 quality‑management certification. For metal enclosures, a zinc coating thickness of 50‑80 µm is a common specification, while PVC enclosures are tested for UV resistance and temperature range from - 20 °C to +70 °C. These standards help buyers match products to local building codes and safety regulations.

Trade and Export Information - Foshan City Kingsun Electrical Co., Ltd.

China is a leading exporter of electrical enclosures, supplying North America, Europe, Southeast Asia and the Middle East. HS chapter 85, particularly code 8538.90, covers “Electrical apparatus for switching or protecting,” which includes metal back boxes and knock‑out boxes. Importers typically require CE or UL certification, IEC‑type testing reports, and RoHS compliance documentation before customs clearance. Shipment is usually packed in double‑wall cardboard cartons, stacked on wooden pallets, and loaded into 20‑ft or 40‑ft containers; FOB or CIF terms are common for bulk orders.

Export logistics from the Guangdong region, where Foshan is located, benefit from well‑developed port facilities and established freight routes. Buyers in the EU often request a Declaration of Conformity (DoC) and an EU‑type test report, while North American purchasers look for UL listing and CSA approval. Temperature‑controlled containers are rarely needed for these metal or PVC products, but moisture‑proof packaging is advised to prevent corrosion of galvanized steel during sea transit.

Sourcing from Foshan City Kingsun Electrical Co., Ltd. - Buyer Guidance

When sourcing metal back boxes from this supplier, request a material test report confirming the galvanization thickness and steel grade, as well as an IEC‑60947 compliance certificate. For PVC pattress boxes, ask for a UL94 V‑0 flame‑retardant test result and a RoHS compliance statement. Verify the dimensions and mounting depth against your project specifications; most 2 Gang metal boxes measure approximately 70 mm × 120 mm × 35 mm and weigh around 0.8 kg per unit.

Samples of the most representative items - such as a 2 Gang metal knock‑out box and a single‑gang PVC pattress box - should be inspected for drilling tolerance, knock‑out panel integrity and surface finish. Request a photograph of the product with serial or batch numbering to trace production runs, and confirm the lead time, which for standard stock items in China is typically 15‑30 days after order confirmation.
