Your One-Stop Wire Mesh Fence Supplier | POLYMETAL
POLYMETAL Diplomat fencing panels are steel ornamental fence panels designed to deliver a premium wrought-iron look with a lower total cost and far less maintenance. Instead of frequent repainting and rust concerns, these panels provide a clean architectural finish, strong visibility, and reliable perimeter control that stays straight and professional across long runs.
Product description
Diplomat fencing panels are engineered for projects that want an upscale appearance without sacrificing structural discipline. The panel design combines rigid rails with evenly spaced steel pickets to create a boundary that is difficult to climb, difficult to cut with common hand tools, and resistant to deformation during transport and installation. The result is a fence line that looks clean from a distance, stays aligned at joints, and supports reliable site management for years.
Product application
Diplomat fencing panels are commonly used for residential communities, commercial properties, schools, parks, factories, warehouses, and public facilities where a decorative but strong boundary is required. The rigid steel construction supports consistent alignment, making it suitable for long straight perimeters, entrances, and landscape-facing frontages.
Prevents climbing performance comes from close picket layout and reduced foothold rhythm on the fence face, limiting toe and finger hold opportunities and discouraging casual climbing attempts. Prevents cutting performance comes from strong steel rails and pickets combined with stable connections that increase cutting difficulty using common hand tools. Resists damage performance comes from a stiff frame structure that reduces flex under impact, making brute-force leverage less effective and helping the fence keep a straight, high-end appearance after installation; for sites requiring even higher anti-climb and anti-cut protection, you can also review our 358 anti climb wire mesh option as an upgraded security solution.
The Top 12 Pitfall headlines you can’t ignore in Diplomat fencing panels (Especially #11)
Pitfall #1: Rail frame chosen for price, not fence height
If the frame is under-sized, the line can look “wavy” and feel weak even if the pickets look fine.
Pitfall #2: Rail thickness is too light for wind and vibration
Long runs amplify movement. Light rails loosen faster and show alignment issues sooner.
Pitfall #3: Upright size looks decorative but lacks stiffness
Thin or small pickets can dent during handling and flex under impact.
Pitfall #4: Upright thickness is under-specced
The fence may arrive straight but deform during transport, unloading, or installation.
Pitfall #5: Picket spacing is inconsistent across panels
Small spacing drift ruins visual uniformity and creates practical “grab points” at certain intervals.
Pitfall #6: Post option is treated as “just support”
A strong panel on a weak post becomes a moving fence—shake, lean, and long-term loosening follow.
Pitfall #7: Post wall thickness is ignored
Thin-wall posts can twist under load, especially near corners, gates, and end posts.
Pitfall #8: Finish system looks good now, then fails at edges
The earliest corrosion often starts at cut ends and corners if coverage and handling protection are weak.
Pitfall #9: Clip/fastener holding strength isn’t matched to height
The fixing system becomes the weak link when panels are tall or wind exposure is high, and if you’re budgeting the full system (including posts, brackets, and installation factors), this guide on garrison fencing cost per metre is a helpful reference for planning.
Pitfall #10: Corners, transitions, and gates are not planned as a system
The perimeter fails where geometry changes—if the design isn’t engineered, the site improvises.
Pitfall #11: Tight tolerances are not controlled—then the site pays twice
When panel width, height, picket spacing, and post drilling/position drift, installation slows down, alignment fights begin, rework happens on-site, and small gaps appear where the perimeter should be clean and continuous.
Pitfall #12: Packing is treated like shipping, not quality control
If panels rub, twist, or stack poorly, damage arrives disguised as “factory defects,” and the job loses time immediately.
Specifications for Diplomat fencing panels

Applications
POLYMETAL Diplomat fencing panels are used for residential communities, commercial buildings, schools and campuses, parks, factories, warehouses, logistics yards, public facilities, and landscape-facing boundaries that require a decorative style with real structural strength. They are especially effective where visibility is needed for patrol, lighting plans, or camera coverage while still maintaining a premium architectural appearance.
Benefits
Diplomat fencing panels improve perimeter control while keeping the environment open and visible, supporting lighting layouts, CCTV coverage, and routine inspections. Correct rail and upright thickness reduce vibration and deformation, helping panels stay straight during transport, installation, and long-term wind cycles. Consistent panel widths, planned post heights, and stable connections reduce installation delays, minimize on-site cutting, and help projects finish faster with a cleaner final line.
Packing
Panels are commonly pallet-packed with protective separation to reduce rubbing, wrapped to reduce scuffing, and reinforced with corner protection to keep stacks stable during loading and delivery. Posts are bundled, wrapped, and palletized to reduce deformation risk. Clips, caps, and other accessories are packed in labeled bags and cartons to reduce loss and speed up site distribution.
Standard
POLYMETAL production for Diplomat fencing panels focuses on dimensional accuracy, spacing consistency, rail straightness control, coating build management, and packing inspection to reduce site rework and protect visual quality. Key control points typically include squareness checks, spacing checks, connection-fit checks with posts and clips, coating coverage on edges and corners, and pallet stability checks to reduce transit damage.
FAQs
What are Diplomat fencing panels?
Diplomat fencing panels are steel ornamental fence panels designed to deliver a premium wrought-iron look with lower maintenance, strong visibility, and dependable perimeter control.
Which rail frames are commonly used?
Common rail frames include 40×40 mm, 45×45 mm, and 50×50 mm. The best choice depends on fence height, wind exposure, and the stiffness requirement of the site.
What picket spacing is common?
Typical picket layouts include 18 uprights per panel at about 100 mm spacing, 17 uprights at about 108 mm spacing, or 16 uprights at about 115 mm spacing, depending on appearance and deterrence level.
Why must post height be higher than panel height?
Posts need extra length for embedment depth or base mounting allowance. A practical planning rule is post height = panel height + 600 mm for stability and long-term performance.
How do I reduce long-term corrosion risk?
Choose a robust corrosion protection system and ensure coating coverage at edges and corners, while using protective packing to prevent early damage before installation.
