Shangixn Caster's latest production run features PU-padded bases, rugged riveted screws, and superior oxidation resistance, offering a cost-effective alternative to conventional galvanized feet.
SHANGHAI – May 27, 2026, 9:00 AM CST – On the morning of May 27, 2026, Shangixn Caster Wheels Co., Ltd., a rising name in the industrial hardware and furniture components sector, began assembling a batch of 10,000 premium carbon steel leveling feet at its integrated manufacturing hub. Designed specifically for furniture applications, these leveling feet combine a black oxide surface treatment, a steel-core base wrapped in a PU pad, and a fixed-structure threaded screw secured by an extra‑tight rivet. The company reports that a long‑term European client has already used this design successfully for three consecutive years, with zero complaints about floor damage or component loosening.
"Traditional leveling feet often create hard contact between furniture legs and floors, leading to scratches, noise, and instability," said a senior production manager at Shangixn Caster. "Our engineering team solved that by adding a PU‑padded 'buffer layer' under the steel chassis. It absorbs micro‑impacts, protects delicate flooring, and still delivers the load capacity needed for heavy cabinets, sofas, and industrial shelving."
The current production batch – exactly 10,000 units – is being assembled under ISO 9001:2025 quality protocols. Each unit undergoes a four‑step inspection: black oxide coating thickness check, PU pad adhesion test, screw torque validation, and dynamic load simulation. Early samples have already been shipped to Würth Group (a leading German fastener distributor) and Fastenal (US-based industrial supply giant) for secondary market distribution. Meanwhile, online B2B sellers including Alibaba.com and ThomasNet have listed the product under the "furniture leveling feet" category, with McMaster-Carr and Grainger showing preliminary interest.
Why Black Oxide Beats Conventional Zinc Plating
According to Shangixn Caster's in-house corrosion lab, the black oxide finish (also known as blackening or gun bluing) offers two major advantages over standard zinc plating:
Superior oxidation resistance – In salt‑spray tests (ASTM B117), the black‑oxide carbon steel lasted 40% longer than conventional zinc‑plated feet before white rust appeared. This makes it ideal for humid environments such as kitchens, bathrooms, or coastal warehouses.
Non‑reflective matte appearance – The dark, even surface blends seamlessly with black metal furniture frames, avoiding the "shiny dot" look of galvanized feet.
"Many buyers assume galvanized is always better, but black oxide actually forms a deeper chemical bond with the steel," explained a sourcing specialist from RS Group (UK‑based industrial parts distributor). "For indoor furniture that doesn't face constant water immersion, black oxide provides ample protection at a lower cost per unit – that's a real value proposition."
Engineering Highlights: Fixed Structure, Riveted Screw, PU Base
The new batch features a fixed, non‑swivel leveling foot design – a deliberate choice for static furniture applications where rotation is unnecessary. The threaded screw (made of cold‑drawn carbon steel, M8×20mm standard with custom lengths available) is joined to the base plate using a high‑pressure riveting process. According to Shangixn Caster's quality report, each rivet is compressed to 3.2 kN of clamping force, ensuring that the screw will never detach from the base even under repeated tightening.
The base itself consists of a stamped iron sheet (2.5 mm thickness) fully encased in a polyurethane (PU) pad. Unlike glued rubber pads that peel off over time, this "iron core + PU wrap" design is molded in a single shot, making the pad inseparable from the metal chassis. The PU material has a Shore A hardness of 85, providing enough elasticity to dampen vibration while resisting oil and abrasion.
European Client Success Story: 3 Years, 100,000+ Units
The most compelling endorsement comes from a furniture manufacturer in Germany (name withheld due to NDA), which has used Shangixn Caster's black‑oxide leveling feet since May 2023. The client produces high‑end modular sofas and TV stands sold through Höffner . Over three years, they have ordered more than 100,000 units across six batches, with a reported field failure rate of less than 0.1%.
"We initially had problems with standard zinc‑plated feet – after six months in customers' homes, the plating would show dull spots and the rubber pads would slide off," said the German client's purchasing manager. "Shangixn's black‑oxide version solved both issues. The PU pad stays perfectly bonded, and the dark finish still looks brand new after three years. Plus, their price per 100 pieces is 18% lower than what we were paying to Italian suppliers."
The client also highlighted the buffer effect of the PU pad: when sofas are pushed against walls or moved during cleaning, the soft pad prevents the steel base from scratching hardwood or tile floors. This single feature reduced after‑sales complaints about floor damage by 73% in the first year.
Market Positioning: Cost‑Effective Alternative to Premium European Brands
While German brands like Ganter and Elesa dominate the high‑end leveling foot market, Shangixn Caster targets mid‑volume furniture assemblers and OEMs who need reliable quality without the "Made in Germany" price tag. By using local carbon steel from Baosteel and PU resin from Wanhua Chemical, Shangixn achieves a low landed cost (EXW Shanghai) – about one‑third the price of comparable European-made black‑oxide feet.
"We're not trying to compete with Ganter on a CNC‑machined stainless steel foot that goes into medical equipment," said the Shangixn sales director. "But for the 80% of furniture applications – bed frames, office desks, retail display units – our black‑oxide carbon steel foot is more than adequate. And with the PU pad, it actually outperforms many all‑metal designs in floor protection."
Supply Chain and Logistics
The 10,000 units assembled today will be packed in anti‑rust VCI poly bags (200 pieces per carton) and shipped via Kühne+Nagel to a consolidation warehouse in Rotterdam, where European sellers including TECHNOLIT and Hafele will distribute them to local furniture factories. Shangixn Caster also maintains stock at Amazon FBA depots in Germany and France for smaller buyers.

Future Plans
Building on this morning's production run, Shangixn Caster plans to launch a stainless steel version (304 grade) for outdoor furniture and a height‑adjustable variant with a 40mm threaded range by Q3 2026. The company is also seeking UL/ETL certification for use in commercial refrigeration units, where leveling feet must withstand extreme temperature swings without loosening.
