Prefabricated Housing Materials

-- Steady & Reliable Manufacturer --

Introduction

The demand for efficient, high-quality Prefabricated Housing Materials is growing rapidly. We supply the core components—pre-painted steel sheets and insulated sandwich panels—that form the walls, roofs, and sometimes the floors of modular and portable homes. Our materials are light, precision-cut, and designed to integrate seamlessly, dramatically speeding up the manufacturing and final assembly process of prefabricated units.

We offer custom color matching and aesthetic finishes, including wood grain and stucco textures, to ensure the finished house is not only strong but visually appealing.

Specifications

Parameter	Material Details
Wall System	Standard EPS/PU Sandwich Panels (50mm, 75mm, 100mm) with tongue-and-groove joint.
Roofing	Lightweight PPGI/PPGL, often in tile-effect or standing seam profiles.
Thickness	Face steel skin typically 0.3mm to 0.6mm, balancing weight and strength.
Fire Safety	Fire-retardant EPS or Rockwool core options available.
Aesthetic Finish	Matte finish and patterned finishes for residential appearance.
Coating Life	SMP or HDP coatings for residential durability (10-15 year warranty).

Aesthetic Consideration: The trend in prefab housing is moving away from the "tin shed" look; our textured and matte finished materials enable modern, attractive designs.

Application

Modular Homes: Primary wall and roofing materials for factory-built residential units.
Site Accommodation: Durable, demountable offices and worker housing.
Emergency Housing: Quick-assembly panels for disaster relief and temporary shelters.
Additions/Extensions: Lightweight and insulating materials for quickly expanding existing homes.

Advantages

High Precision Cut: Materials are supplied with exacting tolerances, ensuring perfect fit during off-site manufacturing and on-site assembly.
Superior Insulation: Integral thermal and acoustic insulation in the panels contributes to a comfortable living environment.
Speed to Market: Reduces the prefab manufacturer's material sourcing complexity and time.
Sustainability: Steel is a fully recyclable material, improving the overall green rating of the housing unit.

Payment & Shipping

Material Kitting: We offer "kit" packing where materials for specific housing models are grouped together for ease of containerization and factory organization.
Incoterms: We regularly ship on DDP (Delivered Duty Paid) terms for many modular home manufacturers, simplifying their supply chain logistics.
Certifications: Materials can be provided with specific regional certifications (e.g., CE, ICC) to meet destination market building codes.

Frequently Asked Questions

Q: How fire-safe are the prefabricated wall panels?
A: Our standard EPS panels are fire-retardant (FR). For enhanced safety required for multi-story residential buildings, we strongly recommend using non-combustible Rockwool core panels.

Q: Can the panels be disassembled and reused?
A: Yes, the tongue-and-groove system allows for the non-destructive disassembly of the sandwich panels, making the resulting house unit highly portable and reusable.
