Import Aluminum Entry Panels With 4'' Ports — Buy in wholesale FOB from Supplier in China

Telsto Development Co., Limited fabricates these aluminum entry panels with 4-inch ports from 3003-H14 and 5052-H32 aluminum alloys, two work-hardened grades selected for their formability and corrosion resistance in enclosure applications. The panels are precision-cut composite sheets with pre-engineered 4-inch diameter ports intended for cable routing, conduit access and equipment integration across electrical and mechanical installations. The 3003-H14 alloy offers moderate strength with excellent weldability, while 5052-H32 provides superior saltwater resistance for harsher environments.

In typical industrial practice, 3003-H14 sheet exhibits tensile strength of 145-195 MPa and yield strength of 115-165 MPa, with H14 temper indicating a half-hard condition from strain-hardening. The 5052-H32 variant, quarter-hard from additional processing, delivers tensile strength of 230-280 MPa with better fatigue performance. Both grades accept standard anodizing and powder coating for surface protection. The 4-inch port dimension aligns with common NPS pipe sizes and standard electrical conduit fittings, simplifying field installation without additional cutting or deburring.

Primary buyers include electrical cabinet manufacturers, HVAC contractors, telecommunications infrastructure installers and commercial construction firms. The lightweight yet rigid panel construction reduces shipping costs compared to steel alternatives while maintaining adequate electromagnetic shielding for most enclosure applications. Buyers should confirm sheet thickness, port spacing, edge finishing and any required flange or gasket interfaces directly with Telsto Development Co., Limited, as these details vary by project specification. Typical surface treatments include mill finish, anodized or polyester powder coating to 60-80 microns dry film thickness.

Telsto Development Co., Limited operates from 3rd Floor, Building E, No.998 Shenbin South Road, Shanghai, China, with postal code 201106 in the Minhang district. The company holds a harbor trust tier, which indicates a basic verification level on the platform where this listing appears. Notably, the supplier's response rate displays as 0.00 with zero average response hours recorded, suggesting either a new listing, inactive account or data collection issue that prospective buyers should factor into their outreach planning.

The listing emphasizes precision fabrication and international trade capability for bulk orders and container shipments, though it does not specify annual output, factory floor space, employee count or specific client references. No ISO, CE or other certification numbers are provided in the source data, despite generic mentions in the marketing description. Buyers should independently verify Telsto's fabrication equipment capability, quality control procedures for port dimensional accuracy, and any third-party audit status before committing to volume orders.
