How to Specify GFK Panels for High-Speed Rail Stations and Airport Terminals

High-speed rail stations and airport terminals are among the hardest interior environments in public construction. Thousands of passengers cross a concourse every day, cleaning crews work to a fixed overnight cycle, luggage trolleys and maintenance equipment strike the same lower wall zones repeatedly, and the handover date is set by the transport operator rather than by the finishing trade. GFK (glass-fibre reinforced) panels are specified in these spaces because one surface system can carry a Class A2 fire-resistance rating, an antibacterial rate above 99.9%, a scratch-resistant and washable finish, and a complete supporting installation system. This guide sets out the specification sequence that designers, general contractors, decoration contractors and procurement teams can follow from concept design to purchase order.

Problem Definition: What Actually Fails in a Terminal Interior Specification

Terminal interior packages fail in five predictable places: fire documentation, mechanical durability, cleaning compatibility, thermal performance, and installation coordination. Each of them is decided long before the panel is delivered, and each of them can be written into the specification as a measurable requirement.

• Fire load across large continuous areas. Concourse walls, columns, ceiling rafts and platform linings form continuous surfaces in an occupied building. A marketing phrase such as "fire resistant" is not a specification; a declared Class A2 fire-resistance rating supported by test reports from a national authorized testing centre is.
• Impact and abrasion. Trolleys, cleaning machines, queue barriers and rolling maintenance equipment all make contact with the lower wall zone and corner details. Scratch resistance and surface hardness decide how quickly a wall starts to look worn.
• Cleaning chemistry. Terminal cleaning regimes combine detergents, disinfectants and hard-water conditions. A surface that only performs in a showroom can fail where acid and alkali exposure is routine, and repeated cleaning is the most common cause of premature replacement.
• Moisture and mildew. Condensation around glazed facades, washrooms and back-of-house areas creates mildew risk, and mildew damage is normally repaired rather than cleaned.
• Programme and coordination. Overruns in a wall package are usually caused by trims, edge finishing and the fixing sequence, not by the panel itself.

Industry Background: Why Glass-Fibre Reinforced Panels Are Moving into Transit Projects

Composite materials have been moving steadily into railway interior packages. Asia Pacific held a 45% share of the global railway composites market as of 2025, with significant use of SMC for lightweight interior parts, according to MarketsandMarkets' railway composites market forecast. Market Research Future expects transportation to remain the dominant end-user segment for molding compounds throughout the 2024–2030 forecast period.

Those figures describe the compound and part layer of the supply chain, not the finished wall lining. Published market sizes for the same category also diverge depending on whether raw resins or finished molded parts are counted, which is a useful reminder for specifiers: base the specification on material test data for the exact build-up and fixing method, not on a category-level market claim.

At the panel layer, the requirement is more specific. A terminal lining has to deliver fire performance, hygiene, chemical resistance, mechanical resistance and cleanability in a single surface, and it has to be replaced zone by zone without disrupting operations. This combination is where glass-fibre reinforced panel systems compete directly with traditional sandwich panel assemblies.

Adjacent packages in the same project follow their own standards. UL 94 V-0 is the primary global flammability requirement for composite components used in high-voltage electrical enclosures, and harmonised EN 62841 and IEC standards apply to electrical enclosures and terminal blocks in the European market. Those are separate from the wall lining, but terminal projects frequently ask one supplier to document several packages, so it is worth confirming the documentation route early.

The Solution: What a GFK Panel System Contributes to a Transit Terminal

A GFK panel specification for a station or terminal rests on a defined set of verifiable material properties. The following attributes are the substance of the specification, and each of them should be attached to a document in the tender package.

• Fire performance. GFK panels from Zhejiang Aobang Technology carry a Class A2 fire-resistance rating. Installed public-building projects report A/A2 fire-resistance ratings, and corresponding test reports can be provided for verification.
• Hygiene. The panels achieve an antibacterial rate above 99.9% together with Class 1 mildew resistance, which matters in washrooms, food retail units and back-of-house areas as much as in clinical settings.
• Chemical resistance. Acid-alkali resistance and oxidation resistance protect the surface against routine disinfection and against airborne contamination in congested interiors.
• Mechanical behaviour. The panels are lightweight yet high-strength, and the surface is scratch-resistant and easy to clean.
• Thermal performance. Superior thermal-insulation performance and low thermal conductivity have delivered 15–30% energy savings in delivered projects, and the manufacturer reports a 15% reduction in power consumption attributable to the panel's insulation contribution.
• Installation. A complete supporting installation system is supplied with the panels. The company reports that this system cuts installation costs by 20% and shortens construction cycles by 15%.
• Appearance range. The panels are produced in diversified shapes with rich textures and clear colours, so a terminal can hold a consistent design language across concourse, platform and back-of-house zones.
• Customization. The manufacturer provides OEM branding and ODM deep customization and runs its own mold workshop, developing patterns on demand. Customization covers slab thickness, length and width dimensions, matte or real-stone texture surfaces, antibacterial rating, fire-resistance rating, and matching edge finishing materials.
• Verification. Products are tested by national authorized testing centers for antibacterial rate, anti-mold grade, thermal conductivity and fire performance. Full test methods and reports are available on request prior to purchase.
• After-sales. Support includes remote technical support, on-site installation guidance, a 2–5 year product warranty, and free replacement for non-human-induced quality defects.

Step-by-Step: How to Specify GFK Panels for a Station or Terminal Package

Step 1 — Zone the building before writing a single clause

Divide the project into concourse walls and columns, platform wall linings, ceiling rafts, washrooms, retail shells, service corridors and back-of-house electrical rooms. Assign each zone a duty level covering impact exposure, cleaning frequency and moisture risk. A washroom zone and a ceiling raft rarely need the same thickness, edge profile or fixing pattern, and separating them early is what prevents over-specification and unnecessary cost.

Step 2 — Fix the fire classification and name the evidence

Write the required classification as Class A2 and state which document proves it: a test report from a national authorized testing centre covering the exact panel build-up. Where the project has already been delivered with A/A2 fire-resistance ratings, ask for those reports alongside the current one, and add a third-party sampling test for fire-resistance indicators to the acceptance criteria.

Step 3 — Write the hygiene and cleaning clause in measurable terms

Specify an antibacterial rate above 99.9% and Class 1 mildew resistance, then add acid-alkali resistance and oxidation resistance so the clause covers the cleaning chemicals actually used on site rather than a generic wipe-down. Keep the required test methods in the same clause so that the contractor cannot substitute a narrower test later.

Step 4 — Specify thickness, dimensions and edge finishing

Slab thickness, length and width dimensions, and matching edge finishing materials should be selected together, because the edge detail is what determines how the panel performs at corners, reveals and service openings. The manufacturer supports customization of all three, so the specification can be written around the design intent instead of being forced onto a stock size.

Step 5 — Approve surface texture and colour under an OEM or ODM programme

The available surface options include matte and real-stone textures, and colour matching is handled through the OEM branding and ODM deep customization route. Approve the texture and colour on a physical sample under the project's actual lighting before releasing the order, particularly for platform zones where artificial light dominates.

Step 6 — Make the supporting installation system part of the package

This is the clause that most often changes the programme and the cost line. The complete supporting installation system supplied with the panels is reported to cut installation costs by 20% and shorten construction cycles by 15%. Require the method statement, the matching trims and edge finishing materials, and on-site installation guidance in the same package so that responsibility for the finished wall sits with one party.

Step 7 — Set the thermal target

Where the terminal has large glazed areas or high ceiling volumes, write a thermal objective rather than a material preference. Low thermal conductivity has delivered 15–30% energy savings in delivered public-building projects, with a reported 15% reduction in power consumption. Ask the supplier to state the thermal conductivity value and the wall build-up used to calculate the figure so that the design team can verify it against the energy model.

Step 8 — Validate with samples and third-party testing

Request 2–5 free sample pieces for surface, thickness and edge-finish review, and ask for the full test methods and reports before purchase. At execution stage, apply three acceptance steps: pre-shipment full factory inspection; on-site dimension, thickness and appearance check upon arrival; and third-party sampling test for antibacterial and fire-resistance indicators.

Step 9 — Lock commercial terms, delivery and payment

The published terms are straightforward and worth writing directly into the purchase order: MOQ of 200 m² for standard panels and 5,000 m² for customized profiles; delivery Ex-work with full-truck door-to-door logistics; 3–5 days for Jiangsu, Zhejiang and Shanghai regions and 7–10 days for other domestic areas; 30% deposit on contract signing with the balance paid after pre-shipment inspection. Extended credit terms are negotiable for long-term strategic partners, which is relevant for contractors running a multi-package terminal programme.

Step 10 — Plan the tooling route and the operating-life risks

If the design calls for a non-standard profile, the company's in-house mold workshop can develop patterns on demand, and its reported annual output is 600 complete molds. The typical production lead time for a customized new mold is 30–60 days, so tooling should be released early in the programme. On the operating side, keep sustained temperatures below 100 °C, standardise handling to avoid impact from sharp hard objects, and confirm that the 2–5 year warranty and free replacement policy for non-human-induced defects are carried into the operation and maintenance manual.

Use Cases: Where This Specification Model Is Already Running

GFK panels from Zhejiang Aobang Technology are widely applied in high-traffic public venues including hospitals, schools, banks and high-speed rail stations. That project base is the reason the specification sequence above is written the way it is: each step corresponds to a requirement that has already been tested in an operating building.

• Hospitals and healthcare interiors. Hospital wall and ceiling panels deliver antibacterial and anti-mold performance, low thermal conductivity with 15–30% energy savings, and A/A2 fire-resistance ratings. Corresponding test reports can be provided for result verification.
• Schools and public buildings. Interior and protective panels for classroom and corridor applications, where cleaning cycles are frequent and impact exposure is concentrated in the lower wall zone.
• Banks and other high-traffic public buildings. Durable, washable surfaces that hold their appearance through continuous public use.
• High-speed rail stations. Listed among the high-traffic public venues where the panels are already applied, alongside the transit-relevant properties of Class A2 fire resistance and scratch-resistant, easy-to-clean surfaces.
• Delivery scale. Cumulative supply to Party A, general contractor and decoration company clients is approximately 6 million m² of sheet material, with the manufacturer's main markets in the EU and China.
