PVC Membrane Fabric Manufacturers

PVC Membrane Fabric – Engineered for Tensile Architecture and Industrial Cover Systems

Zhejiang Hanlong New Material Co., Ltd. is a direct PVC Membrane Fabric manufacturer and OEM factory in China, operating our own weaving and coating plants. We supply high-tensile PVC-coated polyester fabrics for stadium roofing, tensile facades, canopies, exhibition halls, and permanent or semi-permanent membrane structures. Our range is built around dimensional stability, weldability, and long-term weather resistance, with gram weights from standard 650 gsm to heavy-duty 1150 gsm and beyond.

As a vertically integrated supplier, we control yarn selection, weaving, coating formulation, and finishing. This allows us to match the fabric’s mechanical properties to your structural engineering requirements, not just to a generic specification. Our PVC Membrane Fabric line is the backbone of our PVC Coated Tarpaulins family, and it is supported by the same quality system that governs our PVC Tent Fabric and PVC Inflatable Fabric.

Product Range and Positioning

Our membrane fabric range is designed for load-bearing tensile applications. The core product is a high-tenacity polyester scrim coated with PVC, available in multiple constructions and finishes. We offer:

• Standard tensile membrane – 1000D x 1000D, 30 x 30 count, 1150 gsm, for large-span roofs and permanent structures.
• Mid-weight membrane – 1000D x 1000D, 20 x 20 count, 650–750 gsm, for canopies, awnings, and temporary structures.
• Custom constructions – yarn denier, thread count, and gram weight adjusted to meet specific load and deflection criteria.

Each fabric can be supplied with a matt or glossy finish, blockout performance, and a range of surface treatments including PVDF or acrylic for self-cleaning and UV resistance. Flame retardancy options are available to meet B1, M2, or NFPA 701 standards, depending on your project’s local code.

Application Fit and Engineering Context

PVC membrane fabric is the workhorse of tensile architecture. It is used where PTFE or ETFE would be over-specified or cost-prohibitive. Typical applications include:

• Stadium bleacher roofing and canopies
• Atrium skylights and walkway covers
• Exhibition and event halls
• Transportation hub roofs (bus stations, airports)
• Outdoor amphitheaters and shade structures

Compared to PTFE and ETFE, PVC membrane fabric offers the lowest initial cost and the best flexibility for complex geometries. It is easier to cut, weld, and install, making it the preferred choice for projects with moderate budgets or where the structure may be updated. Our fabric is designed to be sewn or high-frequency welded, and we can advise on seam placement and welding parameters based on the coating formulation.

Critical Specifications and Performance Data

When you specify membrane fabric, the key parameters are tensile strength, tear resistance, coating adhesion, and hydrostatic head. Our standard 1150 gsm fabric is engineered to provide:

These values are indicative for our standard 1150 gsm product. For custom constructions, we will provide a detailed technical datasheet based on your required load case and environmental conditions.

Configuration Options and Customization

We understand that every tensile project has unique requirements. Our customization capabilities include:

• Gram weight – from 650 gsm to 1500 gsm or higher, depending on the scrim and coating thickness.
• Yarn denier and count – 500D, 1000D, 1300D, or custom, with thread counts adjusted for strength and flexibility.
• Color – any solid color, printed pattern, or custom color matching to your brand or architectural palette.
• Surface finish – matt or glossy, with optional PVDF or acrylic topcoat for enhanced self-cleaning and UV resistance.
• Flame retardancy – available in B1, M2, NFPA 701, or other standards; we will confirm compliance based on your target market.
• Blockout performance – for applications requiring light opacity, we can add a blockout layer to prevent see-through.

We also offer custom widths and roll lengths to minimize waste during cutting and welding. Our production planning team works with your cutting layout to optimize material usage.

Quality Assurance and Acceptance Testing

Our factory is ISO9001 certified, and we apply a seven-check inspection framework to every production batch. This includes verification of basis weight, yarn density, tensile strength, tear strength, coating adhesion, and water resistance, plus application-specific tests such as UV aging and cold flexibility. We can provide a mill test certificate with each shipment, and we welcome third-party inspections at our plant.

For large projects, we can agree on acceptance criteria before production, including sampling plans and test methods. We recommend specifying a basis weight tolerance of ±5% and a minimum hydrostatic head of 2000 mm for rainproof applications. Our quality team will ensure that the delivered rolls meet these criteria.

Installation, Maintenance, and Service

PVC membrane fabric is designed for easy installation. It can be cut and welded on site using standard high-frequency welding equipment. We provide technical guidance on welding temperature, pressure, and speed to achieve consistent seams. For maintenance, regular cleaning with mild soap and water is sufficient to maintain appearance and performance. Our fabric is resistant to mildew and UV degradation, but we recommend periodic inspection of seams and edges, especially after extreme weather events.

We also offer spare rolls for future repairs or extensions, and our sales team can help you calculate the required quantity based on your structural drawings.

Information We Use to Configure Your Solution

To prepare a precise quotation and technical proposal, we need the following project information:

• Application type – stadium roof, canopy, facade, etc.
• Structural design loads – wind, snow, and dead loads, if available.
• Required dimensions – width, length, and quantity of fabric.
• Environmental conditions – temperature range, UV exposure, and local climate.
• Fire rating requirement – specify the standard (e.g., B1, M2, NFPA 701).
• Color and finish – any specific color code or surface texture.
• Certification needs – any required test reports or certificates.

With this information, we can recommend the optimal construction, coating formulation, and finishing options. We will also provide a sample swatch for your approval before mass production.
