Direct from Northern China's largest ISO-certified manufacturing facility. High performance, complete structural testing, and absolute reliability.
In modern construction and industrial engineering, structural anchoring is not merely a mechanical attachment; it is a critical load-bearing mechanism designed to transfer shear and tension forces into cracked or uncracked base materials. Anchors serve as the fundamental structural link in commercial skyscrapers, heavy industrial processing units, deep transport tunnels, and wind energy infrastructures.
Choosing the correct anchor relies heavily on material science. High-tensile steel, precise thermal tempering, and specialized anti-corrosive coatings determine the lifespan of structural joints. As leading global anchor exporters, we balance raw material cost, mechanical pull-out thresholds, and installation dynamics to produce high-performing fasteners.
"Under severe seismic or high-vibration loads, structural integrity is defined by the weakest connection point. We design anchors to eliminate failure points."
A Globally Recognized Fastening Pioneer and Strategic Manufacturer
Sinsun Hardware, established in 2006, is a leading manufacturer and global supplier of high-quality fasteners. As Northern China's largest producer of Self-Tapping Screws, we operate from a gigantic 30,000 sqm integrated facility that includes modern production zones, a 12,000 sqm smart warehouse (18,000+ pallet capacity), and multi-language customer support centres. Our yearly supply of over 8,500 containers consistently services key global markets such as the Middle East, Southeast Asia, South America, and Russia.
Our production prowess is driven by German-imported machinery, precision Taiwanese technology, and a dependable staff of trained specialists. We offer over 20,000 SKUs of nails, screws, wires, and rivets, each undergoing 12+ stringent quality checks to assure outstanding polish (Ra ≤ 0.4μm), corrosion resistance (1,000+ hours salt spray), dimensional accuracy (±0.02mm), high strength (1,000+ MPa), and consistent hardness (HRC 28-32).
We guarantee reliable and rapid lead times for both standard and special orders by using our integrated facility, optimised inventory, and effective planning. Sinsun Hardware is your strategic partner, committed to delivering quality, innovation, and on-time performance worldwide.
Developing specialized anchoring systems designed for high-stress industries and extreme environments.
Our concrete and sleeve anchors are optimized to support tunnels, bridge rails, and major civil infrastructure. Designed to resist continuous structural dynamic loading and vibration fatigue.
High wind loads demand reliable anchoring systems. Sinsun's expansion and chemical anchors transfer tensile stress safely into external concrete slabs, protecting large commercial building envelopes.
Offshore infrastructure demands premium materials. We provide Duplex Stainless Steel and Zinc Flake coated wedge anchors that resist salt water pitting and corrosion in coastal settings.
Our heavy-duty expansion sleeves provide excellent dynamic load resistance for precision factory machinery. This helps prevent shifting and misalignment caused by operational vibrations.

At SINSUN, our quality control begins at the source. We start with premium raw materials from XING TAI Steel and Ansteel Group (utilizing 10,000+ tons/year of C1022A steel).
We perform in-house spheroidizing annealing and precision wire drawing in our own plant. This end-to-end control, supported by our advanced drawing machines and gas-fired furnaces, ensures superior microstructure, consistency, and performance in every fastener we produce.
At SINSUN, we combine German-engineered multi-station cold heading machines with precision Taiwanese production technology. Our specialized processes, including tail-gripping for drill screws, ensure every fastener is manufactured with utmost accuracy and consistency in our state-of-the-art production facility.
This combination of equipment allows us to maintain tight tolerances (±0.02mm) and achieve production speeds exceeding 1,200 pieces per minute per machine, ensuring large-scale wholesale capacity.
SINSUN operates four dedicated heat treatment lines, allowing for precise and controlled processing time to achieve consistent hardness and enhanced product durability. This in-house capacity ensures both exceptional fastener quality and reliable delivery schedules.
Our advanced heat treatment systems ensure fasteners reach a core hardness of HRC 28-32 and a tensile strength of 1,000+ MPa, preventing brittle fractures in structural environments.
SINSUN offers flexible OEM and ODM packaging tailored to your needs. With a professional packaging team and a 12,000 m² warehouse (18,000+ pallet capacity), we provide custom packaging, 3D design previews, and full logistics support to deliver a seamless experience from production to shipment.
Our ERP-driven warehousing system manages custom inventory dynamically, allowing us to load over 50 TEUs per day with automated sorting machinery operating 24/7.
Unmatched expertise, advanced facilities, and premium-grade steel
Over 200 German-imported multi-station cold heading machines (producing 1,200+ pieces/min/machine) and 4 dedicated in-house heat treatment lines (20-ton/day capacity) guarantee superior screw quality, strength, and durability (fatigue life exceeding 50,000 cycles).
Core steel is sourced exclusively from leading manufacturers like Ansteel Group, utilizing over 10,000 tons of C1022A high-tensile steel annually to guarantee material purity and consistency.
Our 12,000 sqm packaging warehouse enables 24/7 operations with automated sorting (3,000+ cartons/hour) and direct container loading (50+ TEUs/day) for reliable shipping.
