As demand for lightweight, high-performance materials continues to gain traction across multiple sectors, fibre-reinforced composites such as sheet-moulding compound (SMC) are coming into sharper focus. One of the companies aggressively positioning itself is Zhejiang Zhenshi New Material Co., Ltd. (hereafter Zhenshi), which is leveraging its core SMC capabilities to support growth markets such as building & decoration — including fibreglass doors — renewable energy, and electric vehicles.

Growth of the SMC Market & What It Means for Fibreglass Doors

According to recent industry research, the global SMC market is projected to grow steadily, driven by demand in construction, automotive, and renewable energy. One source estimates a compound-annual growth rate (CAGR) of around 4–6 % through the end of the decade. Another study highlights the Asia-Pacific region will see the fastest growth, with China playing a dominant role. 

For fibreglass doors (which use composite materials and often incorporate glass-fibre reinforcements for durability, aesthetics and corrosion-resistance), this implies two key implications:

First, as construction trends emphasise durability, low-maintenance and weather-resistance, composite-reinforced doors become more appealing — and SMC offers a route to mouldable, lightweight panels.

Second, as manufacturers look to reduce weight but maintain strength (particularly in large door panels, industrial buildings or modular construction), the high strength-to-weight ratio of SMC is advantageous. (SMC is defined as a thermosetting resin paste impregnated with chopped glass fibres, fillers and additives, processed into sheets then moulded.) 

Zhenshi: Strategic Developments & Industry Positioning

Zhenshi, founded in 2000, specialises in R&D, production and sales of high-performance fibre fabrics and composite materials including SMC for applications such as wind power, photovoltaics, new energy vehicles, and building materials. 

Recent moves include:

Participation in the Solarex Istanbul exhibition (April 10, 2025) where Zhenshi showcased photovoltaic composite solutions — composite frames, stents, backsheets and portable module bezels — under the banner of “lightweight, low-carbon and scenario”. 

Investment in a new industrial park in Tongxiang, Zhejiang province: an integrated composite-materials facility covering more than 1,000 acres and with total construction area over one million m². The goal: create an intelligent, zero-carbon factory and become the world’s most complete glass-fibre composite material production base. 

For fibreglass door manufacturers or integrators, Zhenshi’s scale and vertical integration suggest potential opportunities: access to large-volume SMC sheet supply, custom composite formulations, and rapid innovation in low-carbon building-material systems.

Trend Drivers & Challenges

Lightweighting & sustainability: Industries like automotive and construction are under pressure to reduce weight, improve fuel/energy efficiency, and meet regulatory or ESG targets. SMC contributes to those goals. 

Asia-Pacific growth: With China’s infrastructure, automotive and renewables sectors expanding, composite consumption is rising. 

Data Bridge Market Research

Composite mouldability & durability: SMC allows complex shapes, good mechanical properties, and corrosion resistance — beneficial for fibreglass doors which may need weather resistance, design flexibility, thermal performance.

Challenges

Cost & competition: Although SMC offers value, competition from other composites or traditional materials (steel, aluminium, wood) remains. Manufacturers must justify premium cost via performance or longevity.

Supply chain & raw-material volatility: Resin and fibre costs, carbon-fibre substitution, and logistics issues can affect margins.

Recycling & sustainability: End-of-life disposal or recycling of thermoset composites remains a challenge, although there is growing interest in bio-based resins and improved recyclability. 

Implications for Fibreglass Door Manufacturers & Specifiers

If you are in the fibreglass door space, consider these take-aways:

Explore sourcing sheet-moulding compound panels (or custom SMC sheets) from composite specialists like Zhenshi. Their scale may enable cost-effective material supply.

Work with material suppliers to emphasise low-carbon, lightweight door panels — a marketing differentiator in commercial/industrial construction.

Consider design for moulding: SMC allows more complex geometries or integrated features (e.g., ribs, integral frames) vs traditional panels, which can reduce fasteners or secondary assembly.

Ask about custom formulations: Zhenshi’s composite R&D capability suggests the possibility of tailored SMC sheets for door applications (fire-resistance, thermal insulation, decorative surfaces).
