Tips for Specifying Razor Wire in a Perimeter Security Tender

To get comparable, usable bids, specify razor wire by its intended application, product construction, dimensions, materials, coating, configuration, quantity, and delivery requirements. State how the wire will connect to the fence or supporting structure, and identify applicable project standards and local safety requirements. Avoid relying on a product name such as “concertina wire” alone: suppliers may interpret it differently. At Song Ming, we recommend issuing a clear specification schedule and asking bidders to identify any deviations against it.

Key Takeaways

• Describe the site conditions, security objective, and installation arrangement before selecting a product configuration.
• Define measurable product characteristics, including wire and blade dimensions, coil geometry, material, and coating.
• Specify packaging, quantities, documentation, delivery points, and the information required with each bid.
• Ask suppliers to list exceptions and confirm compatibility with the project design rather than assuming all products are interchangeable.

Who This Guide Is For

This guide is for procurement teams, security consultants, contractors, and facility owners preparing a perimeter security tender. It is particularly useful when multiple suppliers are being invited to quote and the buyer needs to compare like-for-like offers. It does not replace a site-specific security assessment, structural design, or review of applicable regulations. Treat the examples below as a framework to adapt with the project engineer and local authorities.

Start With the Project Context

Before describing the product, explain where and how it will be used. Relevant conditions can include the fence type and height, exposure to weather or corrosive environments, access constraints, and whether the installation is new or an upgrade. State the security function required, while avoiding unsupported claims that a particular wire configuration will prevent all intrusion. This context lets bidders identify practical constraints and flag mismatches early.

Identify the Installation Arrangement

Clarify whether the wire is intended for a fence top, a wall, a freestanding barrier, or another designed support arrangement. Include drawings or photographs where available, and indicate the expected fixing method, bracket type, support spacing, and interfaces with gates or corners. These details matter because the finished installation depends on both the wire assembly and its supporting structure. If the support design is not yet finalized, mark it as provisional and request supplier assumptions separately.

Tips for Writing Measurable Requirements

1. Name the Product Configuration

Specify whether the tender requires concertina coils, straight razor wire, flat wrap, or another configuration, and explain where each type is to be installed. If the design calls for a particular coil arrangement or profile, define it with a drawing or schedule rather than relying on a broad label. State whether connecting clips, ties, brackets, or other accessories are included in the supply scope. Ask bidders to describe any proposed alternative configuration and explain its compatibility with the project.

2. Define Dimensions and Tolerances

List the dimensions that affect fit, appearance, handling, and installation, and state how each is to be measured. Depending on the design, these may include coil outside diameter, coil length, loop count, blade profile, core-wire diameter, and blade thickness. For format illustration only, a schedule might show a 600 mm nominal coil diameter, 2.5 mm core-wire diameter, and 0.5 mm blade thickness; these are not universal recommendations and must be checked against the design. Where tolerances matter, state the acceptable range and the inspection method instead of leaving bidders to assume one.

3. Specify Materials and Corrosion Protection

Describe the required base material and protective coating, including whether the project calls for galvanized steel, stainless steel, or another documented option. If the tender specifies coating mass, grade, or a recognized standard, name the exact requirement and edition where applicable. Do not assume that terms such as “galvanized” or “heavy duty” define a consistent product across suppliers. Ask for material and coating details in the bid, along with available inspection or product documentation for the offered batch.

4. State Performance Requirements Carefully

Include performance criteria only when they are relevant to the site design and can be assessed consistently. If the project requires tensile properties, corrosion performance, or other test results, identify the test method, sampling approach, and acceptance criteria. A requirement without a defined method can produce bids that appear comparable but are based on different measurements. Where the project has no established threshold, request suppliers to disclose available technical data rather than inventing a pass mark.

5. Clarify Quantity, Packaging, and Scope

Provide quantities in a consistent unit, such as coils, metres, or complete assemblies, and explain whether the quantity includes installation accessories. Identify packaging expectations, labeling needs, and any restrictions on delivery vehicles or unloading. State the delivery location and whether the supplier’s quotation should include freight, insurance, duties, or other costs. If the installation itself is not part of the contract, make that exclusion explicit.

Use a Bid Schedule to Compare Offers

A bid schedule gives suppliers the same fields to complete and makes exceptions easier to identify. Separate mandatory requirements from preferred options, and ask each bidder to mark every requirement as compliant, non-compliant, or subject to clarification. Request the product datasheet and a dimensioned drawing for the exact offered configuration. This reduces the chance of evaluating a general catalogue description instead of the product proposed for the project.

Common Tender Mistakes to Avoid

Using Broad or Conflicting Language

Terms such as “standard size,” “high security,” or “heavy coating” are difficult to evaluate unless the tender defines them. Conflicting dimensions across drawings, schedules, and written specifications can also lead to different interpretations. Check that the product schedule matches the design drawings and bill of quantities. If a requirement is intentionally flexible, state which alternatives are acceptable and how they will be assessed.

Ignoring Interfaces, Safety, and Local Requirements

A product may meet its listed dimensions and still be unsuitable if the fixing arrangement, structure, access, or maintenance plan is not considered. Identify responsibilities for design approval, installation, handling, and inspection, and require compliance with applicable local laws and site rules. Razor wire has sharp edges, so packaging, handling procedures, and installation controls should be addressed by the responsible project team. Do not treat the product specification as a substitute for a safe-work plan or structural review.

Leaving Deviations and Substitutions Unchecked

If bidders can propose alternatives, require a separate deviation schedule that identifies each change and its impact on dimensions, materials, interfaces, and price. Avoid accepting an alternative based only on a similar product name or headline description. Review whether the proposed option fits the drawings and the intended installation. Seek written clarification before award when a response is incomplete or ambiguous.

Recommended Next Steps

Prepare a project-specific schedule covering application, configuration, dimensions, materials, coating, accessories, quantity, packaging, documentation, delivery, and bid deviations. Have the security designer or engineer review technical criteria, and confirm applicable regulatory and safety requirements for the installation location. Then issue the same schedule and drawings to every invited supplier so their responses can be compared consistently. Keep assumptions, exclusions, and unresolved design details visible during evaluation.
