In 2026, coastal and marine engineering will continue to push up demand for stainless steel fasteners. As buyers pay more attention to long‑term safety and low maintenance cost, high‑quality standard stainless steel fasteners will keep stable export growth. For fastener suppliers, improving anti‑corrosion performance, material authenticity and batch consistency is the key to occupying marine and coastal markets.

In March 2026, the management and production teams of Ningbo Gangtong Zheli Fasteners Co., Ltd. held a special quality improvement meeting at its 15,000 sqm factory in Zhenhai Chemical Industrial Zone, Ningbo, China. The event was launched to further enhance product stability and meet growing global demand for high‑strength structural fasteners. During the meeting, the team reviewed production processes, heat treatment controls, and inspection procedures, and finalized a new round of technical upgrades for heavy hex bolts, ASTM A563 nuts, and threaded rods. Led by senior engineers and production supervisors, the company will strengthen raw material testing and batch tracking to ensure full compliance with ASTM, ISO, DIN, and ANSI standards. This initiative aims to support stable delivery for overseas customers in North America, Europe, and the Middle East while strengthening the company’s reputation as a reliable China fastener supplier.

As solar energy continues to grow in popularity, the need for reliable and efficient mounting systems becomes crucial.

Stainless steel screws refer to the shape of screws made by beating stainless steel screw wire, and then the thread is rubbed. The material is stainless steel. Stainless steel screws are divided into stainless steel SUS201 screws, stainless steel SUS304 screws, stainless steel SUS316 screws, etc. according to the material.

Carriage bolts perform well in many applications due to their unique structure and anti-rotation design. Their diverse material selection and surface treatment methods enable them to adapt to different usage environments and needs.
