Your One-Stop Wire Mesh Fence Supplier | POLYMETAL
POLYMETAL Press Spear Tubular Steel Garrison Fencing is a tidy, strong, and highly practical security fence system for commercial and industrial boundaries. It balances deterrence, clean appearance, and long service life by combining square tubular rails, square pickets, and a pressed spear top profile that discourages climbing and tampering.
This type of garrison fencing is chosen when you want a perimeter that looks organized and professional, stays straight over time, and resists everyday abuse—vehicle turbulence, wind load cycles, minor impacts, and repeated site traffic—without quickly turning into a maintenance problem, especially when built from Q235 steel.
Product Description
The base material is hot dipped galvanized steel sheet, which is cut into narrow strips and then roll-formed into square tubes. This forming method improves dimensional consistency, keeps the tube corners crisp, and supports uniform strength across long production runs. After forming, the material is treated with zinc phosphate to strengthen coating adhesion and improve corrosion protection at the surface. It is then rich zinc epoxy coated to build a robust anti-corrosion barrier layer, and finally polyester powder coated to deliver a durable, color-stable finish with strong UV resistance and long-term appearance.
Pressed form spear security fencing is engineered as a neat panel system: the rails are typically 40mm × 40mm square tubes, and the pickets are punched through the rails and welded for rigidity. Square pickets are commonly 25mm (with larger pickets available for higher-security or higher-impact zones). The pressed spear top creates a sharp deterrent line while maintaining a uniform visual rhythm across panels, which is important for large commercial frontages and industrial estates where inconsistent tops and uneven spacing instantly look “cheap.”
Structure and System Logic
The strength of Press Spear Tubular Steel Garrison Fencing is not one part—it is the combination of rail stiffness, picket count, picket spacing, post selection, and connection discipline.
Punch-through pickets increase alignment accuracy and reduce visual waviness. Weld control keeps pickets locked so panels do not rattle or drift. Post sizing and wall thickness protect the fence line from progressive loosening. The coating stack protects the “real life” weak points: tube edges, weld zones, and handling marks that otherwise become corrosion starters.
Characteristics of POLYMETAL Zinc Steel Garrison Fencing
POLYMETAL Press Spear Tubular Steel Garrison Fencing supports fast installation through an assembly-friendly design that improves logistics and transport efficiency. The system is visually harmonious with surrounding environments while still marking a clear boundary line that feels “official” rather than decorative. High-strength tubular structure delivers long service life, and the fence’s impact behavior benefits from a balance of rigidity and controlled flexibility—strong enough to resist deformation, but not so brittle that minor shocks instantly kink the line.
A wide color range supports site identity and zoning. Common choices include green, black, blue, white, yellow, grey, and orange, with full RAL availability for large projects.
Top 12 Dangers You Don’t Know About Press Spear Tubular Steel Garrison Fencing (Especially #7)
Danger #1: Buying “square tube” without locking the wall thickness. Thin wall rails and pickets dent and flex, and once flex starts, fasteners and welds begin to fatigue.
Danger #2: Treating post size as decoration. Posts control the fence line. Under-sized posts make panels look like the problem when the real problem is line movement.
Danger #3: Using wide picket spacing where you need deterrence. Spacing is not only “appearance”—it changes climb risk, pry opportunities, and perceived security.
Danger #4: Weak weld consistency at punch-through points. A few weak welds create a “soft bay,” and soft bays become the first place attackers test.
Danger #5: Ignoring corner and termination reinforcement. Corners multiply force. If corners drift, straight runs quickly look misaligned and start loosening.
Danger #6: Skipping pretreatment discipline under powder coating. Poor zinc phosphate preparation leads to peeling and edge corrosion long before the fence should age.
Danger #7: Cutting connection strength to save cost. When connection quality drops—cheaper brackets, fewer anchors, weaker screws—micro-movement begins. Micro-movement becomes leverage. Leverage opens gaps. Gaps become a routine repair bill and a visible security weakness that invites more attempts.
Danger #8: Mixing specs across one site perimeter. A perimeter is only as strong as its weakest section; attackers target the “easy bay.”
Danger #9: Overlooking transport and stacking abrasion. Scratches at rails and spear tops are where rust starts first if packing is lazy.
Danger #10: Choosing paint-first thinking instead of corrosion-first thinking. Without the right galvanizing base and zinc-rich layers, good color still fails in weather.
Danger #11: Mis-matching panel height to post embed or base plate design. Tall panels on light base plates loosen under wind cycles.
Danger #12: Installing without line control. A fence that is not set straight at the start stores stress in joints, accelerating drift and rattle.

Applications
POLYMETAL Press Spear Tubular Steel Garrison Fencing is widely used for villas, residential communities, gardens, schools, factories, industrial and mining enterprises, financial institutions, sports stadiums, convention centers, squares, roads, balconies, public facility perimeters, boundary fencing, and construction or project site separation where a professional security appearance and consistent long-run line control are required
Benefits Press Spear Tubular Steel Garrison Fencing
POLYMETAL Press Spear Tubular Steel Garrison Fencing delivers strong deterrence from the pressed spear top, dependable strength from square tubular rails and punch-through welded pickets, and long service life from a corrosion-focused coating system. Visibility remains high for patrol and CCTV, wind resistance stays low because the design is open, and the fence line keeps a clean “straight” look that supports commercial frontage aesthetics. When specified correctly, it also reduces ongoing maintenance because the system resists rattling, loosening, and progressive line drift.
Packing and Loading Press Spear Tubular Steel Garrison Fencing
POLYMETAL Press Spear Tubular Steel Garrison Fencing is packed to protect coating quality and prevent spear-top damage. Panels are typically wrapped to reduce abrasion, stacked with separation to prevent rubbing at contact points, and strapped for stable pallet loading. Posts are bundled and wrapped to prevent scratches, while all brackets and fasteners are separated, bagged, and boxed to reduce missing items and speed up site installation counting. This packing discipline is critical because transit damage usually becomes the first corrosion starting point if it is ignored.
Standards and Quality Control
Production control focuses on tube wall thickness consistency, punch-through accuracy, weld stability, panel straightness, coating adhesion, and final color/finish uniformity. Common specification references include galvanizing aligned to AS/NZS 1163 and powder coating aligned to AS/NZS 4506-1998, with powder thickness commonly controlled at a minimum 80 microns for durable outdoor performance. Final inspection commonly includes dimensional checks, visual weld review, surface finish checks, packing verification, and accessory counting—often supported by compatible site hardware such as star pickets.
FAQs Press Spear Tubular Steel Garrison Fencing
What is Press Spear Tubular Steel Garrison Fencing?
Press Spear Tubular Steel Garrison Fencing is a tubular steel security fence system using square rails and square pickets with a pressed spear top profile to deliver deterrence, clean aesthetics, and durable boundary protection.
Why does the pressed spear top matter?
The pressed spear top increases perceived and real climb deterrence while keeping the fence line uniform. It also discourages casual handling and reduces “easy grip” behavior at the top edge.
Is it welded or assembled?
POLYMETAL Press Spear Tubular Steel Garrison Fencing can be supplied as welded panels for maximum rigidity or as a self-assemble modular system for fast installation and logistics efficiency.
Which specs are most common?
Many sites prefer 2400mm-wide panels with 40×40 or 50×50 rails and 25×25 or 30×30 pickets, selecting post sizes and wall thickness based on height, wind exposure, and security level.
What causes early failure most often?
Early failure usually starts as movement: under-sized posts, weak connections, poor installation line control, and the #7 danger—cutting connection strength—turn a “new fence” into repeat tightening, drift correction, and visible security weakness.
