In the exterior wall energy-saving board section, the R&D team focuses on optimizing the two core structures of metal carved board core material and surface coating. The new carved board is upgraded with high-density polyurethane insulation layer, which improves the insulation performance by 22% under the same thickness. It reduces building cooling energy consumption in summer and heating loss in winter, meeting the requirements of ultra-low energy building construction; Replace the surface with a new generation of UV resistant fluorocarbon paint, which is not easy to fade or peel after 10 years of outdoor use, suitable for new rural facade renovation, factory exterior walls, and cultural tourism homestay exterior wall decoration. At the same time, multiple imitation stone and wood texture carved patterns have been added, balancing energy-saving functions and building aesthetics.
The engineering specific plywood has simultaneously completed the iteration of environmental protection formula, comprehensively upgraded the low formaldehyde bio adhesive, and the formaldehyde emission is far lower than the national standard and overseas export testing standards. The moisture-proof process of the board has been optimized for damp construction sites, reducing the problem of moisture stratification during rainy season construction. It can be used in multiple scenarios such as building templates, packaging, and indoor fixtures, and has become the designated choice for green building materials projects in China.
​​​​​​​Modular travel and temporary construction product upgrades focus on lightweight, sound insulation, and recycling. The new spacecraft has re optimized its internal space layout, thickened the broken bridge aluminum sealed doors and windows, and added a passive ventilation and noise reduction system to solve the pain points of condensation and poor sound insulation in outdoor campsites; The framework adopts lightweight high-strength steel structure, reducing the overall weight by 15% and reducing transportation and lifting costs. The economical capsule room simplifies the disassembly and assembly structure, and can be disassembled and transported by a single person. It is suitable for mass layout in youth apartments and temporary rest rooms on construction sites.
A complete set of reinforced anti-corrosion and rust prevention processes for container houses targeting the municipal and overseas infrastructure markets, with the addition of a double-layer epoxy zinc rich primer protective layer, can also be used stably for a long time in coastal high salt spray areas; Supporting modular free splicing, single story, double story, and row layouts can be customized. The flat and emergency dual-use design can be used for long-term office and living, as well as for quick allocation as emergency resettlement housing.

Drawing on feedback from domestic and international clients collected over the past year, the R&D team at Weifang Sandong Building Materials has carried out comprehensive technical upgrades across five core product lines: metal carved panels, construction plywood, space pods, capsule units and container houses. All optimised new variants are now fully mass-produced and available to the market.

For exterior energy-saving panels, the R&D team focused on upgrading two core components: thermal insulation cores and surface coatings. New-generation carved panels adopt high-density polyurethane insulation layers, delivering a 22% improvement in thermal performance at equivalent thickness. The material cuts cooling energy use in summer and heating loss in winter, perfectly matching the requirements of ultra-low energy building developments. Surfaces are finished with upgraded UV-resistant fluorocarbon paint, resisting fading and peeling for up to 10 years of outdoor exposure. A range of new stone and wood grain panel profiles have also been introduced to balance energy efficiency with architectural aesthetics, ideal for rural facade renovations, factory exteriors and boutique tourism homestays.

Construction plywood has also received an eco-formula overhaul with low-formaldehyde biological adhesives. Formaldehyde emissions fall well below national standards and overseas export testing thresholds. Optimised moisture-proof treatment addresses delamination issues common during rainy construction seasons, making the plywood versatile for formwork, packaging and interior fit-out projects. It has become a preferred material for domestic green building initiatives.

Upgrades for modular accommodation and temporary buildings prioritise lightweight design, sound insulation and recyclability. Restructured space pods feature reworked internal layouts, thickened insulated aluminium alloy sealed windows and passive ventilation noise reduction systems, eliminating condensation and poor soundproofing issues frequently reported at outdoor camps. Frames use high-strength lightweight steel, slashing overall unit weight by 15% and cutting transport and hoisting expenses. Cost-effective capsule units feature simplified disassembly structures that can be taken apart and relocated by a single worker, perfect for mass deployment as youth accommodation or temporary site lounges.

Container houses built for municipal works and overseas infrastructure feature full anti-corrosion and rust-proof processing, with dual layers of epoxy zinc-rich primer for long-term service in high-salt coastal regions. Modular flexible assembly supports single-storey, double-storey and connected unit customisation. Dual-purpose design enables long-term office and residential use alongside rapid deployment as emergency resettlement housing when needed.

Every technical upgrade stems from real market pain points rather than superficial conceptual adjustments. All updated products integrate seamlessly with existing project procurement specifications without requiring contractors to adjust construction workflows. Sandong’s lead technical specialist stated that future R&D will continue targeting low-carbon, recyclable construction materials, riding the green building development wave to deliver high-performance prefabricated building supplies for domestic and global markets.

The market for green prefabricated construction materials continues to expand in 2026. With a complete product portfolio covering metal carved panels, plywood, space pods, capsule units and container houses, Weifang Sandong Building Materials provides one-stop solutions for urban renewal, cultural tourism and overseas infrastructure clients across multiple sectors.

2026 marks a pivotal year for scaled-up promotion of prefabricated construction. Domestic urban renewal, rural development, lightweight glamping resorts and Belt and Road overseas infrastructure projects collectively generate massive procurement demand. The industry is shifting focus away from traditional cast-in-place construction toward dry prefabricated assembly systems.

Unlike conventional manufacturers that only produce single categories of panels or temporary housing, Weifang Sandong Building Materials invested early in full-range production lines to build an integrated product system combining exterior thermal insulation panels and modular mobile housing, creating a distinct competitive edge amid fierce industry competition.

Two domestic market segments drive notable demand growth. First, renovation of existing building stock: metal carved thermal-insulation decorative panels are widely adopted for exterior refurbishment of ageing residential compounds and township factories. Faster installation generates far less construction waste, complying with low-carbon construction guidelines. Construction plywood and furniture-grade plywood remain rigid staple demand, sustaining the factory’s core production output.

Second, cultural tourism and temporary resettlement sectors: lightweight space pods and capsule units suit glamping homestays and scenic supporting facilities, while container houses serve construction site headquarters, emergency accommodation and rural retail outlets. Fully detachable and reusable, these modular products drastically shorten project timelines and lower overall construction costs.

Overseas markets show robust demand too. Accelerated urbanisation across Southeast Asia, the Middle East, Australia and other regions pushes local buyers to seek single-source manufacturers capable of supplying both exterior panels and prefabricated housing, eliminating the hassle of coordinating multiple suppliers. Sandong’s full product range can be cleared for export under unified customs declarations. Metal carved panels and container resettlement units are shipped steadily to numerous overseas markets. Rooted in Weifang’s complete local construction material industrial chain, the company gains cost advantages in raw material sourcing, manufacturing, packaging and logistics, delivering cost-competitive products for global buyers.

​​​​​​​Integrated supply delivers tangible convenience for clients. Tourism developers building glamping resorts can source exterior metal carved panels, interior fit-out plywood, accommodation space pods and office container units all from one factory. Municipal renovation contractors and overseas general engineering firms avoid coordinating separate panel and housing manufacturers, with unified support for design, quotation, production and shipment to cut project coordination time significantly.

To cope with sustained demand expansion, Sandong Building Materials has expanded warehouse storage space, upgraded automated production equipment and set up a dedicated foreign trade service team. A full-service system covers pre-sales custom solution design, mid-order production progress tracking and after-sales installation guidance, with tailored product matching schemes for different countries and construction scenarios.

Industry data forecasts steady growth in the green prefabricated construction material market over the next three years. Small manufacturers relying solely on low-price competition will gradually be phased out, while original equipment factories with complete product chains, independent R&D capacity and reliable delivery capabilities will capture larger market share. will keep focusing on its core product lines – metal carved panels, plywood, space pods, capsule units and container houses. Following the broader trend of prefabricated and low-carbon construction, the firm will continue delivering integrated prefabricated building material solutions for clients at home and worldwide.

As international building standards shift toward rigid indoor air quality (IAQ) mandates and zero-carbon building frameworks, the demand for non-emitting, structurally stable interior surfacing has accelerated. SD Panels (Shandong Dongkang Building Materials Co., Ltd.) has expanded its architectural portfolio with the release of its High-Pressure Engineered Composite Wall Panel series.
