There are numerous manufacturers of prefabricated houses in the market, and the quality of their products varies greatly. How to choose a prefabricated house that is both safe and durable as well as cost-effective? This article will sort out the key points for your purchase.

First, clarify the requirements and determine the direction

Before making a purchase, it is essential to clarify first:

Usage: Is it for office, residence or storage? The requirements for thermal insulation, sound insulation and decoration standards vary for different uses.

Usage cycle and frequency: Is it for short-term use or long-term use? Is it necessary to relocate and reuse? This determines your investment in the durability of materials.

Budget range: Setting a clear budget helps you quickly position yourself among numerous options.

Second, examine the core materials and grasp the fundamental quality

Skeleton (light steel keel) : This is the “bone” of a house. The thickness of the steel and the amount of galvanization should be inquired. The thickness of national standard steel is usually no less than 1.0mm. The higher the galvanizing amount, the stronger the anti-rust ability.

Wall panels (sandwich panels) : These are the “flesh and blood” of a house. The core focus is on three points

Panel thickness: The thickness of the upper and lower steel plates affects flatness and impact resistance.

Core material: Common ones include polystyrene (EPS, good insulation but low fire resistance rating), rock wool (fire resistance grade A, good insulation and soundproofing), and polyurethane (PU, with the best insulation performance). Rock wool boards must be selected in crowded places in accordance with safety requirements.

Bulk density: Especially for rock wool boards, bulk density (such as ≥100kg/m³) is directly related to strength and sound insulation effect.

Third, pay attention to craftsmanship and details to determine the user experience

Node connection: Check whether the connections between the columns and the beams, as well as between the wall panels and the frame, are firm and reliable.

Waterproofing treatment: The waterproofing process for the roof, window sills and joints is of vital importance. Good sealant and waterproof design can effectively prevent the trouble of rain leakage.

Door and window quality: Whether the doors and Windows are stable, tightly sealed, and whether the hardware is durable.

Internal configuration: Is the circuit wiring standardized and safe? Have the positions for air conditioning holes and drainage pipes been reserved?

Fourth, choose a reliable manufacturer to ensure full-service support

Qualifications and Cases: Review the manufacturer’s business license, production qualifications, and past successful cases.

Design capability: Can we provide professional design solutions to meet your personalized layout requirements?

After-sales service: Is a clear warranty period provided? Is the installation and transportation professional? Is the response timely when problems arise?

Choosing a prefabricated house is a comprehensive consideration. Starting from your own needs and firmly grasping the three core points of materials, craftsmanship and service, you can avoid traps and select products that meet your expectations.
