Direct Integration with Our Global Steel Manufacturing Plants
Unlike traditional welded wire mesh or chain-link systems, expanded metal mesh fencing is engineered through a continuous slitting and stretching process. This unique manufacturing methodology forms a monolithic structure without joints, welds, or seams. At Sinsun Hardware, we harness our metallurgical expertise and advanced cold-forming technologies to output fences characterized by exceptional anti-climb properties, visual transparency, and structural durability.
By shifting to an ODM manufacturing pipeline, we deliver customizable specifications regarding diamond aperture sizes (long way of design - LWD; short way of design - SWD), strand thickness, and specialized surface coatings. The inherent strength of the mesh relies on the unbroken strands of steel that distribute kinetic energy evenly across the panel, making it virtually impervious to standard cutting tools and impact forces.
Built on data, driven by precision engineering, and backed by international certifications
Deploying high-integrity security fences across major industrial vertical markets
Power grids, water treatment plants, and telecommunication hubs require absolute security. Sinsun's expanded metal fences act as physical barriers that deter trespassers and prevent sabotage while maintaining necessary airflow for equipment cooling.
Engineered with zero-climb mesh geometries, our ODM solutions prevent finger/toe-holds and resist standard wire cutters. Fully integrated with anchor bolts, structural posts, and concertina wire systems to guarantee perimeter containment.
For high-speed rail lines, airports, and marine ports, our fences provide reliable structural boundary barriers. The hot-dip galvanized and powder-coated steel withstands extreme kinetic stresses and constant environmental exposures.
From Premium Raw Material to Finished Defense Enclosures
Our quality control starts at the source. Sinsun utilizes premium raw steel exclusively from XING TAI Steel and Ansteel Group (processing 10,000+ tons annually). In our own plant, we perform spheroidizing annealing, precision cold head forming, and wire drawing, resulting in a steel microstructure that avoids stress fractures during the expansion process.
Every structural batch undergoes detailed inspection processes to secure a surface finish of Ra ≤ 0.4μm, corrosion resistance exceeding 1,000+ hours in salt spray testing, dimensional precision of ±0.02mm, tensile strength of 1,000+ MPa, and structural hardness in the range of HRC 28-32.
Our workshop houses multi-station cold heading machines imported from Germany alongside precision Taiwanese technology. This setup guarantees that all mounting hardware—screws, bolts, and brackets—perfectly match the expanded metal panels, eliminating structural weaknesses in your physical security perimeter.
Our four continuous heat treatment lines allow precise, controlled thermal cycle times. This in-house processing ensures uniform tensile properties throughout the mesh structure, preventing localized structural failures when subjected to dynamic impacts or wind-load pressure.
Adapting perimeter solutions to varying regional standards and global climates
Perimeters in proximity to the sea face rapid salt-air oxidation. Sinsun's expanded metal fences feature heavy zinc diffusion, duplex PVC coatings, and specialty stainless alloys (Grade 316) that resist C5-M high-corrosive conditions.
For regions like Northern Europe and Russia, Sinsun modifies carbon-alloy ratios to maintain ductility down to -40°C. Diamond aperture open-area percentages are optimized to reduce wind drag while retaining maximum physical stiffness.
All Sinsun architectural and security mesh designs comply with key structural regulations, including BS EN 10223, ASTM F1267 (Standard Specification for Metal, Expanded, Steel), and ISO 9001 quality manufacturing management protocols.

See how our custom manufacturing capabilities solve demanding structural security challenges
Challenge: An international logistics carrier needed high-vibration resistant, low-weight structural perimeter boundaries for automated sorting depots.
Sinsun Solution: We supplied customized, lightweight expanded metal mesh panels paired with high-tensile vibration-resistant flange fasteners. Our laboratory conducted extensive tests to ensure the panels resisted cyclic mechanical loads.
Challenge: An offshore oil terminal required perimeter security fences capable of surviving extremely high-humidity, high-saline marine environments without rusting.
Sinsun Solution: We recommended high-grade alloy steel panels coated with a specialized zinc diffusion process and a thermo-set polymer topcoat. We backed the solution with third-party salt spray certification.
Pushing the boundaries of material engineering and structural design
Developing low-VOC and chrome-free surface passivation technologies, such as advanced Dacromet and eco-zinc diffusion, to reduce our environmental impact while maintaining C5-grade corrosion resistance.
Designing physical barrier mesh panels prepared for direct installation of fiber-optic fence sensors and acoustic intrusion detectors, transforming traditional physical barriers into active security assets.
Increasing the efficiency of our continuous slitting and expansion lines to reduce raw material scrap rates to under 0.5%, translating directly into competitive pricing and shorter lead times for global clients.
Technical clarifications on ODM expanded metal fencing and manufacturing services
Expanded metal mesh fencing is manufactured from a single sheet of steel, meaning it has no welds or joints that can rust or break under impact. It cannot be easily cut with standard wire cutters and provides higher security, better wind load distribution, and a clean, modern aesthetic.
Yes, we specialize in custom ODM tooling. We adjust the long way of diamond (LWD), short way of diamond (SWD), strand width, and sheet thickness according to your security requirements. We also offer customization for matching structural posts and assembly accessories.
We offer hot-dip galvanizing conforming to EN ISO 1461, along with multi-layer powder coatings and duplex PVC coatings. These coatings undergo 1,000+ hours of continuous salt spray testing in our QA laboratory to verify long-term resistance in high-salinity C5-M marine conditions.
While our high-speed manufacturing lines are optimized for high-volume orders, we maintain flexibility for infrastructure prototypes and major engineering trials. Please reach out to our team with your exact specifications, and we will formulate a viable manufacturing schedule.
Standard sizes take approximately 4 to 6 weeks. Customized ODM orders requiring custom tooling, specialized alloys, or multi-stage coating processes average 6 to 8 weeks. We provide clear schedules and tracking updates through our integrated ERP system.
Supporting components for secure mesh mounting and structural frames
Your project deserves a fencing partner who understands the critical link between material formulation, precision expansion, and structural security.
