Industrial perimeter fencing should be specified from the site threat and operating plan. A warehouse, utility yard or manufacturing facility may need boundary control, restricted access, camera visibility and controlled gates, but the required system will differ by site exposure, response capability and asset criticality.

MaiFa Fence publishes the defining 358 mesh at 76.2 x 12.7 mm with 4.0 mm wire, plus multiple panel widths/heights, post sections and coating routes. These facts support a product schedule; they do not replace the site's security assessment or structural design.

Start with the site: define what the fence must deter, how intrusion is detected, how responders reach the location and where gates or services interrupt the line. Then request a fence system that fits those conditions.

Industrial RFQs are clearer when responsibilities are assigned as well as products. State who supplies the site survey, perimeter layout, design inputs, foundation design, gate automation, access control, earthing or bonding assessment, installation and final inspection. Identify documents that the fence supplier must submit and those provided by other disciplines. Use a single interface register for corners, walls, drains, utility crossings, vehicle gates and emergency exits. This prevents a generic panel quotation from being mistaken for a complete security solution. It also allows MaiFa to price its documented panel, post, fixing and gate scope without accepting responsibility for information that was never provided. Any requested security performance should name the test or assessment, evidence issuer and exact tested configuration.

1. Provide an RFQ basis-of-design

Input	Questions to answer	Quotation effect
Threat	Climbing, cutting, tool access, vehicle approach or casual trespass?	Drives height, mesh, fixings and additional measures.
Layout	Runs, corners, slopes, buildings, culverts and gates?	Controls panels, posts and specials.
Environment	Wind, terrain, soil, coastal/industrial exposure?	Controls posts, foundations and coating.
Operations	CCTV, lighting, detection, patrol and emergency access?	Creates mounting and interface requirements.
Evidence	Which tests, standards or project records are required?	Defines the submittal schedule.

2. Specify the physical fence line

State total length, height, ground gap, panel width preference, post spacing basis, top treatment and termination at buildings or other barriers. Show drainage channels, uneven ground and places where a gap could form below the mesh. If stacked panels or unusually tall systems are proposed, require a coordinated post and fixing design.

3. Protect connections and openings

The fixing drawing should show clamps or cover bars, bolt positions and any tamper-resistant requirement. Gates need equivalent infill and controlled clearances. Service penetrations, drainage openings and interfaces with walls can become weaker than the main 358 panel unless they are included in the security review.

List every pedestrian, swing, sliding and emergency gate.
Define lock, access-control and monitoring interfaces.
Coordinate camera and lighting sight lines with posts and toppings.
Identify cable routes and equipment brackets before coating and fabrication.
State who designs gate posts, foundations and automation supports.

4. Specify coating from exposure

MaiFa publishes hot-dip galvanizing after welding, Galfan and polyester powder coating over galvanization. State the required route, colour and inspection basis. Pay attention to welds, cut edges, post bases, fasteners and water traps. Avoid claiming a fixed lifespan without exposure, coating and maintenance evidence.

5. Industrial-site quotation schedule

Package	Required submittal
Fence panels	Mesh, wire, dimensions, quantity, tolerance and coating.
Posts/foundations	Sections, walls, spacing, loads/inputs, interface and responsibility.
Fixings/specials	Tamper-resistant details, corners, ends, slopes, service interfaces and spares.
Gates	Complete drawings, hardware, access-control interfaces and supports.
Evidence/inspection	Project-required reports, material/coating records, inspections and change control.
Packing/commercial	Package protection, weights, container plan, Incoterm, schedule and warranty scope.

6. Copy-and-send RFQ

Please quote a complete 358 industrial perimeter system for attached site layout. Threat and operational basis: [summary]. Total length [m], height [mm], gates [schedule], top/ground details [requirements]. Use 76.2 x 12.7 mm mesh and 4.0 mm wire unless an approved alternative is identified. Propose panel width, posts, fixings and foundation interface using supplied wind/terrain/soil inputs. Include CCTV/detection/access-control interfaces, coating, approved drawings, required evidence, inspections, packing and [Incoterm] price to [named place].

Frequently asked questions

Is 358 mesh enough for every industrial site?

No. Threat, height, posts, foundations, fixings, gates, ground/top details and operations determine the system.

Can cameras be added later?

They may be, but early coordination reduces blind spots and avoids field drilling or coating damage.

What is the weakest part of a perimeter?

It depends on the design; gates, service openings, ground gaps and terminations require the same review as panels.

Should performance claims appear in the RFQ?

Only with a defined requirement and evidence applicable to the exact offered configuration.

Use MaiFa's 358 options within a site-led design

MaiFa can quote the published 358 panel, post and finish options after receiving the site layout and project requirements. The RFQ should make every interface and evidence obligation visible.
