Engineered to deliver exceptional load-bearing performance, code compliance, and structural integrity across diverse concrete, drywall, and masonry substrates.
Within structural engineering, critical connections demand absolute safety and predictable load behavior. Anchoring technology represents the vital link between structural elements and concrete, masonry, or light-gauge wall panels. As global infrastructure continues to scale and seismic design criteria tighten, the demand for advanced anchoring systems has evolved beyond simple mechanical fasteners to highly customized, load-certified fastening systems.
Sinsun Hardware stands at the forefront of this industrial shift. Leveraging over a decade of metallurgy expertise, in-house vertical manufacturing, and precision testing protocols, we supply civil, industrial, and residential developers worldwide with anchoring solutions that bridge the gap between architectural vision and structural safety.
Our large-scale manufacturing infrastructure in Northern China underpins Sinsun's commitment to speed, compliance, and product variety.
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 centers. Our yearly supply of over 8,500 containers consistently services key global markets such as the Middle East, Southeast Asia, South America, and Russia.
Over two decades of systematic technological iteration, production line scale-up, and international accreditation.
Sinsun began with a singular focus in 2006: to build a factory dedicated to self-tapping screws. This foundational specialization established our core expertise from the ground up, setting the standard for wire processing and metal forming.
The year 2012 marked a pivotal step for Sinsun with the establishment of our Export Department. From that point forward, our specialized fasteners began reaching international projects, expanding our quality systems to international standards.
In 2015, Sinsun expanded its control over quality by adding four spheroidizing furnaces for raw material processing and in-house wire drawing capabilities. This strategic upgrade allowed us to control structural fastener properties beginning from the wire rod raw material.
Our production capability was enhanced in 2018 with new German multi-station cold heading machines. Concurrently, we grew our product line to include a variety of drill tail screws and mechanical anchors, solidifying our engineering foundation.
Sinsun's growth in 2021 was defined by two key metrics: reaching 36,000 tons in annual production and fulfilling international orders with over 1,100 export containers. This output proved our capacity to service massive global distribution networks.
To ensure rapid delivery for our clients, we optimized our stocking systems. By running a large, centralized warehouse space, we guarantee responsive supply chains for global mechanical anchor and fastener distribution networks.
The addition of four heat treatment lines in 2025 significantly boosts our production capacity. This directly translates to greater consistency in hardness, tensile strength, and structural performance, keeping Sinsun at the leading edge of fastening technology.
How our integrated metallurgy, cold forging technology, and strict QC testing protocols produce industry-leading anchors.
We source premium raw materials directly from elite providers like XING TAI Steel. Spheroidizing annealing and wire drawing are handled entirely in-house. This comprehensive control ensures a uniform material microstructure, optimal cold formability, and structural consistency prior to forging.
Utilizing high-end German multi-station cold heading machinery combined with Taiwanese tooling systems, Sinsun produces anchors with strict dimensional tolerances of ±0.02mm. Our complex processes, including advanced tail-gripping for self-drilling parts, eliminate micro-cracking and material fatigue.
Our four continuous heat treatment lines precisely manage carburizing and tempering cycles to achieve core hardness levels of HRC 28-32. Surface coatings (ranging from Hot Dip Galvanizing to specialized multi-layer zinc) undergo 12+ QC evaluations, ensuring corrosion resistance exceeding 1,000 hours in salt spray testing.
From structural heavy-duty load paths to high-vibration seismic zones, Sinsun anchors guarantee engineered load transfer.
Tunnels, highway barriers, structural columns, and utility line installations require absolute anchor reliability. Our high-tensile wedge anchors and heavy-duty expansion sleeves transfer high tension and shear loads deep into concrete, resisting cyclical loads and dynamic stress over decades of continuous operation.
Securing architectural facade brackets to structural concrete requires precise anchor margins. Sinsun's sleeve and chemical anchoring assemblies provide secure, vibration-resistant points of attachment, neutralizing wind shear force and thermal expansion differentials on building envelopes.
Modern commercial framing uses composite, gypsum, and light metal studs. Our Molly anchors and specialized drywall toggles distribute clamping forces evenly across hollow cavity walls, preventing base material breakout, and assuring stability for interior equipment and wall fixtures.
For structural engineers and procurement directors, regulatory compliance is non-negotiable. Sinsun's manufacturing plants operate under strict ISO 9001:2015 frameworks. Our structural anchors are routinely tested in accordance with ICC-ES and ETA protocols, validating tensile capacity under both cracked and uncracked concrete models.
Through our dedicated packaging teams, we deliver custom OEM and ODM packaging options, including custom barcoding, 3D design previews, and color-coded box layouts. Supported by our 12,000 sqm smart warehouse, we offer rapid logistics, stable lead times, and comprehensive documentation to facilitate seamless customs clearance across European, American, Middle Eastern, and Russian borders.
Our commitment to engineering progress drives our R&D efforts to build next-generation structural fastening systems.
