Tubular Steel Picket Fence Shocking : 9 Hidden Risk Point

Tubular Steel Picket Fence is one of the most common ways to secure residential, commercial and industrial perimeters. It looks clean, simple and strong, and in open or exposed locations it can even work together with wind barriers to calm wind flow around sensitive areas. But behind the neat vertical pickets there are multiple technical details that can easily turn into risk, pitfall and long-term cost if they are chosen carelessly.

POLYMETAL designs Tubular Steel Picket Fence systems to close these dangerous gaps. By controlling fence height, rail frame size, upright tube selection, spacing, post dimensions and the way the fence interacts with any added wind barriers or screens, POLYMETAL helps you avoid the kind of structural mistake that only becomes visible when the fence starts to lean, rust or fail under impact and wind load.

Why Tubular Steel Picket Fence Mistakes Are So Dangerous

When a fence is under-designed or badly specified, you do not always see the problem on day one. The real danger appears slowly:

• Panels begin to rattle in strong wind.
• Posts move inside cracked footings.
• Uprights bend where people climb or push.
• Coating fails and corrosion eats into the steel.

These are classic loss and damage pattern that come from a few key oversights:

• Wrong fence height for the real threat level.
• Rail frame too light for span and wind.
• Upright size not matched to impact and security needs.
• Upright spacing not controlled, creating safety and liability gaps.
• Post size too small for the load.
• Post height and footing not suited to soil and wind conditions.
• No clear standard for series and models, making future extensions difficult.
• Inconsistent fabrication quality between panels.
• No full specification overview, only vague marketing lines.

POLYMETAL tackles these danger point directly with clear, repeatable data and model ranges.

Core Design Elements POLYMETAL Controls

For POLYMETAL Tubular Steel Picket Fence, the key structural elements are:

• Fence height – typically 1200 mm, 1500 mm, 1800 mm and 2100 mm.
• Fence width – common panel lengths such as 2400 mm, 2700 mm and 3000 mm.
• Rail frame – square hollow section (SHS) 40 × 40 mm, 45 × 45 mm or 50 × 50 mm.
• Uprights – 16 × 16 mm, 25 × 25 mm or 30 × 30 mm square tubes.
• Upright spacing – controlled at 100 mm to balance safety and visibility.
• Post height – matched with a 2400 mm fence post for the typical fence heights.
• Post size – 60 × 65 mm, 75 × 75 mm, 80 × 80 mm and 100 × 100 mm square posts.

Instead of mixing these sizes at random on each project, POLYMETAL builds complete model lines so that you can choose a configuration that matches your risk profile and budget, but still stays within proven structural rules.

How to Read the POLYMETAL Specification Tables

Each specification table below shows:

• Model – suggested code name for easy ordering and reference.
• Fence Height – visible height of the Tubular Steel Picket Fence panel.
• Fence Width – standard panel length to suit common bay spacing.
• Rail Frame – size of the main horizontal rails (SHS).
• Upright Size – size of the vertical pickets (SHS).
• Upright Spacing – distance between uprights (all kept at 100 mm).
• Post Height – matching post to use with the panel (2400 mm typical).
• Post Size – cross section of the post.

All dimensions are in millimetres (mm). You can adjust or rename the model codes to match your internal system, but keeping the structure and sizes is critical if you want to avoid structural defect and failure.

POLYMETAL Tubular Steel Picket Fence – Residential Series (Table 1)

Designed for low to medium risk residential applications where appearance and basic security are required without extreme loading.

Table 1 – POLYMETAL Tubular Steel Picket Fence Residential Series

These models give you a safe starting point for typical domestic boundaries, gardens and low-rise developments without under-sizing the structure.

POLYMETAL Tubular Steel Picket Fence – Standard Security Series (Table 2)

This series steps up strength for schools, public areas and light industrial boundaries where higher loads and more frequent contact are expected.

Table 2 – POLYMETAL Tubular Steel Picket Fence Standard Security Series

These combinations are ideal where you need a stronger fence but still want to control project cost and keep a clean architectural look.

POLYMETAL Tubular Steel Picket Fence – High Security Series (Table 3)

For higher risk locations, POLYMETAL increases both fence height and post size, while keeping consistent 100 mm upright spacing for safety and anti-climb performance.

Table 3 – POLYMETAL Tubular Steel Picket Fence High Security Series

These models suit exposed perimeters, main boundaries to industrial zones, or any site where a clear security signal and structural strength are both required.

POLYMETAL Tubular Steel Picket Fence – Industrial & Heavy Post Series (Table 4)

This series focuses on heavier posts and frames for gate lines, corner bays, vehicle access points and other high-load positions where failure would be a serious hazard.

By using these POLYMETAL Tubular Steel Picket Fence tables as a strict design checklist, you greatly reduce the risk of hidden drawback, gap or oversight in your perimeter system. Instead of gambling on unknown “standard panels,” you work with clear data, proven patterns and durable finishes such as galvanizing plus powder coating, turning your fence from a potential hazard into a long-term protection and performance boost for your site.
