Import 90 Degree Rectangular Stanchion Base — Buy in wholesale FOB from Supplier in China

This 90 Degree Rectangular Stanchion Base, model ZB1808-22, is an investment-cast marine hardware component produced by Wudi Zhibo Metals Co., Ltd. in Shandong Province, China. It accepts 7/8 inch (22 mm) tube stock and is manufactured from stainless steel 316, a molybdenum-bearing austenitic grade with enhanced chloride corrosion resistance over standard 304. The base features a mirror-polished surface finish, achieved through mechanical polishing and buffing processes that produce a reflective, smooth face suitable for visible deck installations. The 90-degree geometry indicates a right-angle mounting configuration, with the rectangular footprint providing a flat, stable interface for rail stanchion attachment to deck or bulkhead surfaces.

Stainless steel 316 is the standard material specification for marine rail hardware exposed to salt spray and intermittent immersion, with typical composition of 16-18% chromium, 10-14% nickel, and 2-3% molybdenum per ASTM A351/CF8M. Investment casting, also known as lost-wax casting, permits near-net-shape production of the base with consistent wall thickness and internal radii that would be difficult to machine from solid billet. The mirror polish is not merely cosmetic: it reduces surface microporosity where chlorides initiate pitting, and facilitates visual inspection for stress-corrosion cracking. A second size variant, 1 inch (25.4 mm), is also catalogued, suggesting tooled patterns exist for common imperial tube dimensions in yacht and commercial vessel construction.

The primary application is yacht and small-craft deck railing, where this base joins vertical stanchions to horizontal decks or toe rails at a right angle. Shipwrights, marine outfitters, and chandleries represent the core buyer segments. The supplier also produces complementary hardware (hinges, eye plates, shackles, turnbuckles) from the same 316 castings, which simplifies corrosion-matching across a vessel. Minimum order quantity is stated as one piece, indicating stock-item availability rather than project-custom production. Buyers should confirm current stock levels, exact base dimensions (length, width, bolt-hole pattern and diameter), and whether fasteners are included or must be sourced separately. The packaging specification of OPP bag plus carton is standard for marine hardware exports from Shandong, though sea-freight crating requirements should be discussed for containerised orders.

Wudi Zhibo Metals Co., Ltd. operates from No.161 Delixi Industrial Zone in Binzhou, Shandong Province, China. The company's listed address places it within an established industrial zone, though no specific facility size, founding year, or employee count is provided in the source data. The supplier identifies itself as a manufacturer of stainless steel marine hardware and rigging hardware, with a product range that extends beyond this stanchion base to include anchors, deck fillers, fishing rod holders, eye bolts, shackles, turnbuckles, thimbles, and carabiners. The trust tier of 'harbor' and a response rate of 0.00% with zero average response hours are recorded; buyers should note that these signals indicate limited or no recent communication activity through the platform channel, and direct outreach may be necessary to assess current operational status and responsiveness.

The supplier's product description emphasises stock availability and low minimum order quantities across its range, positioning itself as a source for both replacement-part orders and small-batch outfitting projects. No certifications (ISO, marine classification society approvals, or material test certificates) are mentioned in the source material, nor are specific export markets or reference clients named. The investment-casting specialisation suggests in-house or closely partnered foundry capability, though the exact production arrangement is not disclosed. Buyers evaluating this supplier should request current material certificates for the 316 stainless steel, dimensional inspection reports for the casting patterns, and clarification on whether mirror polishing is performed in-house or subcontracted. The lack of response data means due diligence through direct contact, sample ordering, and third-party verification is advisable before committing to volume purchases.
