Spear Top Tubular Fencing Shocking 18 TRAPS Dangerous Loss

Spear Top Tubular Fencing is often selected because it delivers a sharper security profile than flat-top tubular fencing while keeping a clean architectural look. The problem is that many fences look “the same” in photos, but behave very differently on site. POLYMETAL supplies Spear Top Tubular Fencing as a matched system—panel geometry, rail frame size, wall thickness, upright profile, upright count, post pairing, and powder-coated finish are controlled together so installers don’t have to “fix it on site” with uneven spacing, noisy joints, or crooked lines.

Product Description: POLYMETAL Spear Top Tubular Fencing

POLYMETAL Spear Top Tubular Fencing (also called garrison or millennium style in some markets) is manufactured using welded tubular rails and uprights, finished with powder coating for durable appearance retention. The spear-top profile increases perceived deterrence while keeping the fence line visually professional for public-facing boundaries.

Typical panel widths are 2400mm (also common: 2375mm) and 2450mm where site set-out requires it. Common heights include 1200mm, 1500mm, 1800mm, 2100mm, and 2400mm.

Picket/upright profiles are typically 16×16mm, 25×25mm, or 30×30mm, matched with rail frames such as 40×40mm, 45×45mm, or 50×50mm depending on stiffness demand. Upright spacing is controlled to a 100mm target, and upright quantity is commonly specified as 16 pcs (≈115mm gap), 17 pcs (≈108mm gap), or 18 pcs (≈100mm gap) to lock the “security feel” and gap discipline across long runs.

Post planning is the difference between a straight fence line and a “snake line.” POLYMETAL pairs each panel build with posts sized for stability (60×60mm, 65×65mm, 75×75mm, 80×80mm, or 100×100mm) using wall thickness options of 1.6mm, 2.0mm, and 2.5mm. To support embedment and long-term alignment, the post height rule is applied consistently: post height is greater than panel height by 600mm.

Applications: Spear Top Tubular Fencing

Spear Top Tubular Fencing is commonly used for villas, schools, parks, commercial frontages, industrial sites, warehouses, estate perimeters, and public facilities where a clean look must still communicate strong boundary control. The spear top style is frequently specified where deterrence perception matters, such as higher-traffic edges, street-facing boundaries, and sites that want a “security feel” without the harsh look of chainwire.

Benefits: What a Correct Spear Top System Delivers

When the rail frame is sized correctly and post pairing is not under-built, the fence line stays straight across long runs instead of forming visible wave lines. When upright quantity and spacing are locked, the fence presents as consistent and professional instead of “patched.” When powder coating is controlled and protected in packing, the finish stays acceptance-ready instead of arriving scratched or chalking early. The net benefit is not only security—it is lower rework risk, fewer complaints, and smoother handover on tight schedules. For buyers comparing compatible panel formats and supply options, tubular metal fence panels for sale fits naturally into the same system-first decision process.

Packing: How POLYMETAL Prevents “Arrival Damage”

Packaging is treated as part of the product, not decoration. A practical packing method is metal pallet + plastic films between each panel + metal bondages + an outer protective film layer, with cartons and metal corners added to reduce scratch and impact damage. Clips, screws, and nuts are packed in small plastic bags and then packed into carton boxes to avoid missing-part delays that force unsafe on-site improvisation.

Standard, Delivery, and Manufacturing Control

A stable Spear Top Tubular Fencing outcome depends on controlled geometry (panel squareness, consistent hole/picket layout, repeatable spacing), controlled welding quality, and controlled finish curing. Production follows a practical flow: raw material selection → cutting → punching holes → shaping → welding → surface treatment and powder coating → inspection. Typical delivery time for standard builds is within 15 working days after receiving the deposit, with OEM options available to match project drawings and site set-out plans.

Top 18 TRAPs for Spear Top Tubular Fencing (Especially #15)

TRAP #1: Buying by photo and ignoring rail thickness

Thin rails flex, joints loosen, and the fence line becomes noisy and visibly uneven.

TRAP #2: Choosing 40×40 rails where 45×45 or 50×50 is required

Under-sized frames amplify vibration and reduce long-run straightness.

TRAP #3: Treating 0.8mm vs 2.0mm upright thickness as “small”

Thin uprights bend during transport and never look straight again.

TRAP #4: Mixing upright profiles (16×16 / 25×25 / 30×30) in one run

Even if the color matches, the visual pattern does not—rejection risk rises.

TRAP #5: Saying “100mm spacing” without locking upright count

Factories build by picket count and jig positions; “approx spacing” produces inconsistent gaps.

TRAP #6: Using 16/17/18 layouts randomly across the same frontage

Spacing differences are instantly visible in public-facing projects.

TRAP #7: Under-building posts and expecting panels to stay straight

Weak posts twist and rotate, which loosens fixings and creates wave lines.

TRAP #8: Ignoring post wall thickness

1.6mm posts can be fine for light use, but higher fences often need 2.0–2.5mm to resist rotation.

TRAP #9: Forgetting the post height rule (Panel + 600mm)

Shallow embedment is the fastest route to leaning over time.

TRAP #10: Accepting poor squareness

Out-of-square panels cannot produce a clean straight line, no matter how good the installer is.

TRAP #11: Treating corner and end posts as “standard”

Movement often starts at corners and spreads down the run.

TRAP #12: Thinking “assembled” is always equal to welded

Assembly can work, but only when joint control is engineered; weak joinery creates rattles.

TRAP #13: Letting weld quality slide because it “looks fine” on delivery

Weak fusion reveals itself after vibration, handling cycles, and thermal movement.

TRAP #14: Ordering mixed batches without locking geometry

Small jig differences create visible steps and uneven spear alignment.

TRAP #15: The hidden LOSS—your spear top fence looks great, then fails acceptance after install

This is the budget killer. Under-sized rails and posts, inconsistent upright density, or weak finish control can turn into rattles, leaning, and a wavy frontage after normal handling. That triggers rejection, rework, replacement panels, delayed handover, and reputation damage when timelines are already tight.

TRAP #16: Buying “powder coated” without controlling cure and thickness

Cheap coating scratches during installation, then looks old fast—black and dark colors show everything.

TRAP #17: Ignoring packing protection

Transport rub marks become permanent appearance defects before the first panel is installed.

TRAP #18: Buying panels only instead of a complete system plan

Panels without matched posts, fixings, spacing plan, and finish targets create on-site improvisation—and improvisation creates failure points.

FAQs: Spear Top Tubular Fencing

FAQ 1: What sizes are common?

Common heights are 1200mm, 1500mm, 1800mm, 2100mm, and 2400mm, with common widths of 2400mm and 2450mm (also used: 2375mm / 2400mm market formats).

FAQ 2: Which rail frame should I choose?

40×40mm suits lighter boundaries, 45×45mm is a strong general upgrade, and 50×50mm is preferred when rigidity and quiet joints matter most.

FAQ 3: What upright count should I specify?

Typical layouts are 16 pcs (≈115mm gap), 17 pcs (≈108mm gap), or 18 pcs (≈100mm gap). Locking count is how you lock the final look.

FAQ 4: What is the post height rule used in the tables?

Post height is panel height + 600mm to support embedment and reduce long-term leaning risk.

FAQ 5: How are panels packed for shipping?

Common packing uses metal pallets and protective films between panels, with outer wrapping and corner protection. Hardware is packed by set to prevent missing parts.
