Fabric Reinforced Rubber Sheet Price Factors and Purchasing Guide for Engineering Projects

Published on 2026-10-14

Hengshui Zhanhe Engineering Rubber Co., Ltd. supplies fabric reinforced rubber sheet and related engineering rubber products to contractors, distributors and infrastructure projects worldwide. A rubber sheet with fabric plies inside. The plies carry tension and tear loads while the compound seals, cushions and grips, so it works where a plain rubber sheet would tear or squeeze out.

This article explains the working principle, main types, typical applications, installation points, selection criteria, standards and frequently asked questions about fabric reinforced rubber sheet, and is intended for engineers, purchasers and project managers.

1. What Is Fabric Reinforced Rubber Sheet?

A rubber sheet with fabric plies inside. The plies carry tension and tear loads while the compound seals, cushions and grips, so it works where a plain rubber sheet would tear or squeeze out.

Working principle: The product works through elastic deformation and mechanical interlock to provide reliable sealing or load transfer.

3. Typical Applications

4. Installation and Construction Points

  1. Cut to the drawing, allowing margin for clamping edges and bolt holes, and punch or drill holes cleanly
  2. Grind the substrate sound, flat and free of oil, derust steelwork and apply the matching adhesive
  3. Lay from one end, pressing out air, and stagger joints in multi-layer work with laps of at least 100 mm
  4. Use clamp plates or washers and tighten evenly without stretching or wrinkling the sheet
  5. On tunnel portals fit the numbered segments and check contact against the ring and segment extrados
  6. Verify the sealing line is continuous before the machine is launched

6. Standards and Quality Control

Fabric Reinforced Rubber Sheet is manufactured and inspected according to applicable national and industry standards. Hengshui Zhanhe Engineering Rubber Co., Ltd. carries out batch inspection before delivery, and inspection certificates together with third-party test reports (where required by the project) can be provided.

Typical standards applied to this product family include Chinese national and transportation industry standards; equivalent international standards can be referenced upon request.

7. FAQ

Q: Are more plies always better?

A: No. Extra plies raise tensile and tear strength but the sheet becomes stiffer and less able to follow curves. One to three plies suit gaskets and linings; four or more suit loaded or tear-prone positions.

Q: Can a tunnel portal sealing sheet be reused?

A: It is treated as a single-use consumable, one set per launch or reception. The sheet is bent and worn as the machine passes and is generally not reused. Store it away from sunlight, oil and sharp folds.

Q: Can it be bonded to steel?

A: Yes. Derust and roughen the steel, degrease it, apply the matching primer or adhesive, coat the sheet face too, let both flash off and press together. On important joints combine bonding with bolted clamp plates.

Q: How do I judge the quality of a sheet?

A: Cut a section: plies should be evenly spaced with no exposed fabric, blisters or weak bonding. When pulled apart, rubber should remain on the fabric rather than peeling cleanly. Check hardness and tensile strength against the test report; sheet with exposed plies or layers that separate by hand should not be used in loaded positions.

8. Price Factors

Quoted by weight or by area. Cost depends on the compound, since NBR and EPDM cost more than NR, the number and type of fabric plies, thickness, vulcanising and any cutting or punching. A standard 5 mm natural rubber sheet with fabric is commonly quoted at 18-35 yuan per kg; oil-resistant and thick multi-ply grades are higher, and shaped parts made to drawing may carry tooling cost.

Packing: standard export packing (woven bags, pallets or wooden cases). Delivery terms: EXW, FOB, CFR, CIF or DAP as agreed. Payment terms: T/T, L/C or other terms subject to negotiation.
