Explore our premium range of factory-engineered condensing units, evaporators, and advanced PUR/PIR/EPS sandwich panels.
In the modern sustainable construction era, Expanded Polystyrene (EPS) Sandwich Panels have emerged as a cornerstone for structural insulation. With energy regulations becoming increasingly stringent across the European Union, the Americas, and the Asia-Pacific region, the demand for cost-effective, high-thermal-efficiency building envelopes is at an all-time high.
EPS sandwich panels feature a lightweight, rigid core of expanded polystyrene sandwiched between two metal sheets, usually galvanized or pre-painted steel. This configuration delivers structural stability, superior thermal insulation (with thermal conductivity values λ ranging from 0.033 to 0.040 W/m·K), and ease of rapid installation.

A data-backed engineering comparison between EPS, Polyurethane (PUR), and Polyisocyanurate (PIR) cores.
Choosing the correct core material depends heavily on the project’s specific constraints regarding thermal resistance values, fire safety regulations, load-bearing capacities, and budget allocations. EPS panels represent the most cost-effective solution with balanced properties, while PUR and PIR offer higher thermal performance and advanced fire classification for heavy-duty environments.

How our localized raw material network, continuous production capabilities, and logistics channels guarantee supply stability.
Equipped with advanced automatic continuous double-belt lamination systems, our production line processes sheet-metal uncoiling, profiling, core insulation bonding, curing, and automated cutting simultaneously. This reduces labor errors, maximizes dimensional accuracy, and keeps production schedules reliable.
Based in Shaanxi, a key industrial corridor in China, we work directly with top steel manufacturers and raw polymer distributors. This close proximity stabilizes our supply chain and insulates our customers from sudden global material price fluctuations.
Our factories leverage China's Belt and Road logistics network, using direct rail freight to Central Asia and Europe, alongside major deep-water ports for shipping to Southeast Asia and the Americas. This ensures cost-efficient, on-time deliveries worldwide.
Engineered for high performance across diverse climates, environments, and specialized industrial sectors.
In hot and humid regions, maintaining thermal integrity at loading docks and sorting centers is critical. Our EPS and PIR panels keep interior temperatures consistent, reducing cooling losses and protecting cargo during high-turnover logistics operations.
For fresh fruits, vegetables, and crops, preserving freshness requires precise humidity and temperature controls. Our panels are built with food-grade steel coatings and anti-corrosive properties, making them ideal for farm-side cooling rooms and agricultural processing centers.
In pharmaceutical, electronics, and food-processing fields, dust-free environments are vital. Our seamless panels feature custom tongue-and-groove joint layouts that prevent dust accumulation, simplify sanitation, and withstand aggressive chemical cleaners.
The construction industry is shifting toward a circular economy and lower embodied carbon footprint. YuanShengHeTong's product development roadmap focuses on reducing environmental impact while maximizing panel durability:
A journey of continuous innovation, facility expansion, and technological breakthroughs since 1996.
Our founder started the business from refrigeration equipment marketing and installation.
With our first factory completed in Shaanxi, we produced our first cam-lock sandwich panels.
The second factory in LanZhou completed, our business started to cover the whole north-west market in China.
The Shaanxi factory relocated to a larger fields, now we possess with 120 acers area with 8 advanced workshops.
With more advanced technology in insulation panel industry, we input our first automatic split-joint production line.
Our second advanced automatic production line put on stream, we reach to a higher productivity and efficiency with better quality.
With the responsibility of sustainability, we are now moving into a eco-friendly factory.
Our manufacturing protocols are certified by leading global classification societies, ensuring international quality compliance.
Expert insights on selecting, installing, and maintaining EPS sandwich panels for industrial applications.
EPS panels are highly cost-effective and light, making them ideal for budget-conscious projects requiring reliable thermal control. PUR/PIR panels offer slightly better thermal conductivity and higher fire resistance, suitable for specialized sub-zero facilities or structures with strict fire safety codes.
Our standard EPS panels use fire-retardant raw materials that meet B2 classification standards under EN 13501-1. For advanced fire protection, we produce PIR panels that achieve B1 ratings, offering self-extinguishing properties and low smoke emission.
Yes. We supply specialized metal skins, including PVDF-coated steel, stainless steel (SUS304/SUS316), and anti-corrosive coatings, to withstand high moisture, salinity, and chemical cleaning in demanding environments.
With our continuous dual production lines, standard manufacturing takes 10 to 15 days. Global transport times vary depending on the destination port, typically ranging from 15 to 30 days via sea freight, and 7 to 12 days via rail freight to Central Asia.
