Composite Decks and Railing Market Report 2025

The composite decks and railing market size has grown rapidly in recent years. It will grow from $3.95 billion in 2024 to $4.36 billion in 2025 at a compound annual growth rate (CAGR) of 10.4%. The growth during the historic period can be attributed to the rising popularity of outdoor living spaces, increased adoption in commercial applications, a surge in renovation and remodeling projects, greater availability of advanced composite materials, and improved cost-effectiveness compared to traditional wood.

The composite decks and railing market size is expected to see rapid growth in the next few years. It will grow to $6.39 billion in 2029 at a compound annual growth rate (CAGR) of 10%. The growth projected for the forecast period can be attributed to the rising trend of sustainable and green building practices, increasing demand for customizable outdoor designs, expanding construction activities in emerging economies, growing preference for composite materials over traditional wood, and greater availability of innovative composite materials. Key trends during this period include advancements in co-extrusion technology for improved durability, development of capped composite decking, innovations in recycled material use for eco-friendly products, progress in fire-resistant composite materials, and the creation of modular railing systems for easier installation.

The growth of the composite decks and railing market is expected to be driven by increasing residential construction activities. Residential construction involves developing or renovating housing structures such as single-family homes, apartment complexes, and residential buildings. This rise is mainly due to population growth, which increases demand for housing and leads to new residential developments to accommodate more households. Composite decks and railings benefit from this trend as homeowners and builders seek durable, low-maintenance outdoor solutions for new homes and renovations. For example, in July 2023, the Australian Bureau of Statistics reported that the number of dwellings under construction in the March quarter of 2023 rose to 240,813 from 240,065 in 2022. New houses accounted for 103,778 in 2023, up from 101,240 the previous year. Therefore, rising residential construction activities are driving the growth of the composite decks and railing market.

Key players in the composite decks and railing market are integrating innovative technologies such as heat-mitigating infrared (IR) reflective technology to reduce surface heat buildup, enhance comfort in hot climates, and improve the overall outdoor living experience. This technology involves surface treatments or material formulations that reflect infrared radiation from sunlight, reducing heat absorption. For instance, in February 2025, US-based Trex Company Inc. expanded its Trex Select line to include performance-engineered boards featuring proprietary SunComfortable IR heat-mitigating technology, becoming the first mid-tier composite decking product to incorporate this innovation. These boards are designed with refined aesthetics and on-trend colors such as malted barley, millstone, and whiskey barrel, engineered to reflect infrared radiation and keep deck surfaces cooler in direct sunlight.

In March 2025, US-based James Hardie Industries plc acquired The AZEK Company Inc. for $14 billion. This acquisition aims to create a one-stop shop for exterior and outdoor living products by combining AZEK’s expertise in timber-composite decking and railing with James Hardie’s leadership in fiber cement cladding and trim. The integration is expected to accelerate above-market growth and enhance customer offerings in the North American construction industry. The AZEK Company Inc. specializes in low-maintenance composite decking, railing, and outdoor products under the TimberTech brand.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s recommendations and conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the construction sector, particularly in materials procurement and project costs. Higher duties on imported steel, aluminum, lumber, and machinery have driven up expenses for builders, contractors, and infrastructure developers, leading to increased project bids and delayed timelines. Construction equipment manufacturers face similar challenges, with tariffs on essential components and raw materials inflating production costs and squeezing margins. Additionally, retaliatory tariffs in international markets have curtailed exports of U.S.-made construction equipment and materials, further affecting profitability. The sector must now prioritize local sourcing, modular construction techniques, and supply chain diversification to control costs and ensure project viability amid ongoing trade uncertainties.

Composite decks and railings are outdoor building materials composed of a mixture of wood fibers, plastics (often recycled), and bonding agents. These materials are processed into boards and railing systems that replicate the look of natural wood while offering superior durability and resistance to rot, mold, insects, and fading.

The main types of composite decks and railings include capped composites and uncapped composites. Capped composites feature wood-plastic cores covered by a protective polymer cap that guards against moisture, fading, stains, and scratches. Common materials used in composite decking are polyethylene (PE), polypropylene (PP), wood-plastic composite (WPC), polyvinyl chloride (PVC), and fiber-reinforced plastic (FRP). These products find applications in decks, railings, fencing, privacy screens, and pool surrounds. They are distributed through various channels such as online retailers, home improvement stores, contractors, and landscapers, serving a diverse range of end users across residential, commercial, and industrial sectors.
