Tensile Membrane Structure
Technical Data & Engineering Specifications
Full material specifications, steel grades, structural performance data, and engineering capabilities for every Jutent project.
Membrane Material Specifications
Jutent supplies tensile membrane structures using two primary high-performance fabric types: PVDF (Polyvinylidene Fluoride) and PTFE (Polytetrafluoroethylene). For applications requiring partial shading with airflow, mesh fabric is also available. All membrane materials are available in a wide range of standard and custom colours — white is the most widely specified, but custom colour matching is available upon request.
Full material data sheets (MDS) for each membrane grade are available for download on our Documentation page →
غشاء PVDF
The standard choice for commercial and institutional projects. Strong UV resistance, self-cleaning surface, and cost-effective across all grades.

For applications requiring partial shading with natural ventilation. Blocks 50–90% solar radiation depending on shade factor.
Jutent works with internationally recognised suppliers including Duken, Ferrari, Sattler, Hightex, and Castillo.
Steel Structure Specifications
All steel components are fabricated to international structural standards. Jutent primarily uses two steel grades, each mapped to the equivalent international standard.
| Jutent Grade | US Equivalent | EU Equivalent | Yield Strength | Tensile Strength | Typical Use |
|---|---|---|---|---|---|
| Q355B | ASTM A572 Gr.50 | EN S355JR | ≥ 355 MPa | 470–630 MPa | Main columns, beams, primary frames |
| Q235B | ASTM A36 | EN S235JR | ≥ 235 MPa | 370–500 MPa | Secondary members, purlins, bracing |
Surface Treatment & Anti-Corrosion
Structures are designed with bolted connections as the primary assembly method. Column base connections allow on-site welding to accommodate foundation tolerances.
The structural steel frame carries a 2-year warranty covering fabrication quality and structural integrity under normal use conditions.
Structural Performance Data
Structural Calculation Standards
Our structural calculations are prepared in accordance with Chinese national standards (GB 50009 / GB 50017). For projects requiring international standards such as ASCE 7 (US) or AS/NZS 1170 (Australia / New Zealand), we can accommodate this upon request.
Complete calculation documentation is provided with every project. If your local authority requires review by a locally licensed engineer, we supply the full dataset — load inputs, section properties, and analysis outputs — to support that process.
Engineering & Design Capabilities
Every Jutent project is backed by a full engineering workflow — from initial concept modelling through to fabrication drawings and on-site installation guidance.
Deliverables Included with Every Project
Finite element analysis of a tensile membrane canopy structure — stress distribution visualisation
Quality Assurance
Quality control is built into every stage of our production process — from raw material inspection through to pre-shipment checks.
Coating thickness inspection on fabricated steel components prior to shipment
الأسئلة الشائعة
What membrane weight do you recommend for a project in Southeast Asia?
For standard commercial projects in Southeast Asia, we typically specify 1050 g/m² PVDF as the baseline. For coastal locations or areas with typhoon exposure, we upgrade to 1300 g/m² and increase the steel frame section sizes accordingly.
Can you provide a structural calculation report for permit applications?
Yes. We produce structural calculation reports based on Chinese national standards (GB 50009 / GB 50017). International standards such as ASCE 7 or AS/NZS 1170 can be accommodated upon request.
ما هو الفرق بين غشاء PVDF و PTFE؟
PVDF membrane: PVC base with PVDF coating, 10-year warranty, cost-effective for commercial projects. PTFE membrane: glass-fibre base with PTFE coating, Class A fire rating, 15-year warranty, for landmark structures.
Can I specify a custom colour for the membrane?
Yes. Membrane is available in a wide range of standard and custom colours. White is the most widely used, but we can accommodate custom colour requirements.
What wind speed can your structures withstand?
Our structures are designed to withstand wind speeds of 200 km/h and above, subject to structural calculation. Every project receives a site-specific structural analysis.
