Aluminum and steel can both be used for picket, ornamental and boundary fence systems. The correct choice depends on exposure, structural demand, security objective, appearance, handling, maintenance plan, local code and total installed system—not on a universal claim that one material is always better.

MaiFa Fence’s client product matrix identifies powder-coated tubular aluminum and galvanized, powder-coated tubular steel as product families, with custom size, colour and tube thickness available. Its website publishes detailed steel panel dimensions and a current aluminum panel range. Buyers should treat each quotation as a defined configuration and compare like with like.

Neutral selection rule: choose aluminum where low mass and resistance to red rust are important; choose steel where higher stiffness, robust security geometry or heavier-duty components are required. In either case, verify alloy or steel grade, tube walls, panel design, coating, fasteners, gates and project loads.

1. Compare the materials by project condition

Decision factor	Aluminum fence	Steel fence
Corrosion mechanism	Contains no iron, so it does not form red iron rust; coating and compatible fasteners still matter, especially in chloride exposure.	Requires a defined protective system such as galvanizing and powder coating; cut edges, welds and damaged coating need attention.
Weight and handling	Lower density generally reduces component weight for comparable geometry.	Higher density generally means heavier panels but may support robust sections and security detailing.
Structural selection	Alloy, temper, section and wall must be selected for spans, wind and gate loads.	Steel grade, section and wall must be selected; stiffness cannot be inferred from material name alone.
Appearance	Suited to clean picket, slat and ornamental profiles with powder-coated colour options.	Suited to picket, ornamental and security profiles with galvanized/powder-coated finishes.
Maintenance	Inspect coating, fasteners and chloride deposits; wash where the environment requires.	Inspect coating damage, welds, cut ends, post bases and fasteners; repair protective layers as specified.

2. Use MaiFa’s published ranges carefully

MaiFa’s current aluminum content publishes panel heights from 900 to 2500 mm and lengths from 1200 to 2400 mm, with anodized, powder-coated and wood-colour finishes mentioned. Because exact alloy, profile sections, walls and picket spacing vary by design, request a project drawing and quotation schedule rather than applying one website value to every aluminum product.

For a galvanized steel picket product, MaiFa publishes Q195 or Q235 steel, wall or fence-thickness options of 0.8, 1.2, 1.5 and 2.0 mm, heights from 900 to 2500 mm and lengths from 1200 to 2400 mm. Published picket sections are 16 × 16, 19 × 19 and 25 × 25 mm; rails 30 × 30 to 50 × 50 mm; posts 50 × 50, 60 × 60 and 65 × 65 mm. The listed finish is galvanized and powder coated, with posts, brackets, bolts, nuts and anti-theft screws described as accessories.

These steel values apply to that published product family, not automatically to every steel fence. For both materials, the signed quotation and approved drawing should control the order.

3. Start with exposure and corrosion detailing

Describe distance from saltwater, industrial pollution, de-icing salt, irrigation, pool chemicals, soil contact and cleaning regime. Aluminum does not produce iron rust, but chloride exposure, trapped water and incompatible metals can still cause local corrosion. Steel needs a defined galvanizing and coating system, plus protection at welds, drilled holes and field cuts.

Use fasteners compatible with the panel, post and coating system; isolate dissimilar metals where the design requires it.
Avoid water traps and define drainage at rails, caps and post bases.
State whether fabrication occurs before the final protective finish.
Define coating thickness or mass, colour, gloss, sampling and repair of transport or installation damage.
Include a maintenance and cleaning note for the actual environment.

4. Compare structural capacity by design, not material label

A light steel panel can be less rigid than a well-designed aluminum panel, and a heavy steel system can be much more robust than a decorative aluminum system. Compare the actual alloy or grade, tube section, wall, rail and picket spacing, panel width, post spacing, connection detail and foundation. Provide wind, terrain, soil and gate data so the system can be selected for the project.

Large swing or sliding gates deserve separate engineering attention because leaf weight, hinge moments, automation and wind area may govern the gate posts and foundations. Do not assume the standard line-post detail is suitable at a gate.

5. Check safety, security and visibility requirements

Define whether the fence is decorative, a property boundary, a pool barrier, a school or public-space barrier, or a security perimeter. State the required height, clear openings, climbability restrictions, top profile, ground clearance, gate self-closing or locking functions and local code. Product photographs do not establish compliance with a particular jurisdiction.

MaiFa can manufacture customised dimensions and colours, but customisation should follow the project requirement. A change in picket spacing, rail position or gate hardware may affect safety, loads and approval evidence.

6. Compare quotations on an equal basis

Quotation section	Information required for both materials
Material	Aluminum alloy/temper or steel grade; profile/tube sections, wall thicknesses and tolerances.
Panel/post system	Finished height/width, picket/rail/post geometry, spacing, caps, brackets, fasteners and foundation interface.
Finish	Pretreatment, anodizing/galvanizing where selected, powder type/thickness, colour, gloss, inspection and repair.
Gates	Clear openings, leaf/frame, posts, hinges, locks, stops, self-closing/automation and hardware.
Evidence/QA	Approved drawings, requested material and coating records, dimensional/weld/assembly inspection and pre-shipment photos.
Packing/commercial	Protective film or separators, pallets/crates, weights, loading plan, unit prices, Incoterm, lead time and warranty scope.

7. Copy-and-send comparison RFQ

Please quote aluminum and galvanized steel alternatives for [project/application] at [location]. Fence height: [mm]; panel length: [mm]; total length: [m]; gate schedule: [details]. Exposure: [coastal/industrial/inland/poolside]; wind/terrain/soil inputs: [details]. For each option, state alloy/temper or steel grade, all profile sections and walls, picket spacing, post spacing, connection/foundation interface, coating sequence/thickness, colour and compatible fasteners. Provide separate weights, itemised prices, approved drawings, requested material/coating records, maintenance guidance, packing/container plan, [Incoterm] to [named place], production schedule and warranty scope. Identify all technical differences between the two offers.

Frequently asked questions

Is aluminum always better near the coast?

Aluminum avoids red iron rust, but alloy, coating, drainage, chloride deposits and fastener compatibility still matter. Compare the complete exposure-specific systems.

Is steel always stronger?

Material strength alone does not define a fence. Compare grade, section, wall, span, post spacing, connections and foundations.

Can MaiFa customise colour and size?

The client product matrix and website describe custom size, colour and tube-thickness options. The approved drawing and quotation should define the final configuration.

What steel sizes does MaiFa publish?

One current galvanized picket product lists heights of 900–2500 mm, lengths of 1200–2400 mm and several picket, rail, post and wall options.

What must be checked for a pool or public-space fence?

Local requirements for height, openings, climbability, ground gaps, gates, latches and self-closing functions. Do not infer compliance from a generic product page.

Ask MaiFa for two fully defined alternatives

MaiFa offers both tubular aluminum and galvanized, powder-coated steel fence families. A useful comparison asks for the same project layout and performance conditions, then requires each offer to disclose material, geometry, finish, hardware, weight, packing and exclusions.
