Huilian maintains its own R&D team. For calcium sulfate floor development, Huilian collaborates with Nanjing University and the Research Institute of Wood Industry of CAF, making substantial R&D investments to develop high-strength, quality-stable calcium sulfate products and establish industry quality standards. For all-steel floor products, Huilian partners with the American ASM Group to incorporate foreign production technology and molds.

1 | Main Material | Calcium Sulfate Raw Material | Selected natural α-special grade high-strength gypsum powder (CaSO4 1/2H2O)Advantages: Environmentally friendly, high purity, good strength and toughnessDisadvantages: High cost | Ordinary gypsum powder mixed with ordinary cement or fly ashAdvantages: Low costDisadvantages: Low purity, low strength and toughness, not environmentally friendly |
Paper Pulp | Unbleached sulfate coniferous wood pulpAdvantages: Natural wood pulp, environmentally friendly, no impurities, no odor, high floor strengthDisadvantages: Relatively high cost | Recycled paper pulp from waste newspapers and kraft paperAdvantages: Low costDisadvantages: Many impurities, odor, not environmentally friendly, low floor strength | ||
Adhesive | Shanghai Yechuan Tai GlueAdvantages: Environmentally friendly, non-polluting, strong adhesionDisadvantages: Increased cost | Ordinary resin adhesiveAdvantages: Relatively low costDisadvantages: Not environmentally friendly, poor adhesion | ||
Steel Plate | Galvanized steel plate from ShougangAdvantages: High hardness, good flatness, anti-bending and anti-rust performanceDisadvantages: Increased cost | Ordinary steel plate from small steel millsAdvantages: Relatively low costDisadvantages: Many impurities, poor rigidity, average anti-bending and anti-rust performance | ||
2 | Production Process | Calcium Sulfate Base Material | Single-piece formulation and production: Each raw material is stirred separately, then precisely weighed through an automatic electronic system according to formula requirements before entering the mixing chamber.Advantages: Ensures uniform quality of each product, stable quality, small density errorDisadvantages: Multiple processes, time-consuming operation, increased cost | Various raw materials are directly mixed and stirred in batchesAdvantages: Simple process, convenient operationDisadvantages: Uneven product quality, inconsistent component content, large density variations |
3 | Key Production Equipment | Drying Oven | Two automatic belt-type drying units from Germany's BISON Company. The 30-meter drying channel has five levels, with electronic digital temperature control maintaining constant temperature throughout.Advantages: Constant temperature process, less than 1℃ variation across all levels, ensuring even drying and consistent moisture contentDisadvantages: High equipment and maintenance costs | Self-made traditional drying channel or kilnAdvantages: Low equipment and maintenance costsDisadvantages: Poor temperature control with variations exceeding 10℃, resulting in uneven drying. Excessive temperature causes over-drying, reducing strength; insufficient temperature leads to high moisture content, causing poor bonding, delamination, bubbling, and steel plate rusting |
Note: Base material quality directly affects floor load-bearing capacity and safety. Besides raw materials, moisture content control is crucial, requiring 3%–5% for qualified materials. Too low moisture content leads to brittleness and reduced strength; too high causes poor bonding and delamination. Domestic manufacturers using traditional drying equipment often struggle with large-scale production, especially for major engineering projects with tight deadlines, facing challenges in supply capacity and quality control.

1 | Main Material | Steel Plate | Huilian uses premium materials meeting strict standards. Floor plates use Tangsteel and Baosteel cold-rolled steel with >90HRC hardness, ensuring rigidity, flatness, and anti-bending properties. High-quality deep drawing plate forms the bottom, with superior edge formation.Advantages: High hardness, excellent flatness, superior anti-bending and anti-rust performanceDisadvantages: Increased cost | Ordinary steel plate from small steel millsAdvantages: Relatively low costDisadvantages: Many impurities, poor rigidity, average anti-bending and anti-rust performance |
Filler | Imported foaming equipment and agent with pure cement slurry, ensuring dense grouting and uniform foaming for superior load-bearing strength without fracture sounds.Disadvantages: Lower production efficiency, higher production cost | Low-grade cement mixed with fly ash and ordinary foaming agentAdvantages: Low costDisadvantages: Reduced floor strength, produces fracture sounds when stepped on | ||
2 | Production Process | All-Steel Floor | 1) Enhanced process including post-stamping and welding shape treatment for precise dimensions and surface flatness2) 64 edge welding points (50% more than standard 40) for superior edge load-bearing capacity3) Unique design with 64 traditional plus 32 protruding bottom balls, strengthening flat areas and enhancing overall, ultimate, and distributed load capacityDisadvantages: High R&D investment, multiple processes, time-consuming operation, increased cost |
As an export-oriented manufacturer and ASM Group manufacturing base, Huilian adheres to national SJ/T10796-2001, American CISCA, and British MOB testing standards. The company implements a rigorous three-inspection system and maintains its own testing facilities for concentrated load, rolling, distributed load, impact, and electrostatic performance testing. Each batch undergoes strict outgoing inspection to ensure quality. This comprehensive quality management system results in slightly higher costs compared to other manufacturers.
