Container House Specifications

The specifications for container houses cover multiple aspects such as design, production, construction, and acceptance, and must comply with national and industry standards, including requirements for dimensions, structure, materials, fire protection, and acceptance.

1. Dimensions and Structural Specifications

Container houses are divided into standard and non-standard types, with dimensions and weights varying by specification. For example, a 20-foot standard container has an external dimension of 6055mm (length) × 2435mm (width), with an internal height of 2591mm or 2790mm after assembly, and a weight of no less than 1850kg. Structurally, it employs a cold-rolled welded steel frame, with a 100mm thick insulation layer laid on the base floor. The floor is a composite of 4mm thick steel sections, 2mm thick steel horizontal members, rock wool board, galvanized steel sheet, plywood, and PVC flooring, achieving a flammability rating of B1 and a smoke density rating of Q1.

2. Material and Performance Specifications

Materials must meet requirements for fire protection, smoke prevention, and wear resistance. The insulation layer uses either rock wool board with a density of 120kg/m³ (Class A non-combustible) or Neopor R EPS board with a density of 18kg/m³ (Class B1 difficult-to-burn), both certified by CE & GL. Wall panels consist of a 50mm thick outer layer of galvanized color steel sheet, a 50mm thick Neopor R polystyrene board insulation layer, and an inner layer of galvanized color steel sheet, colored white (RAL9001 color card). For doors and windows, sliding windows use UPVC frames with 5mm clear glass, and entrance doors are double-sided galvanized color steel sheet doors with aluminum alloy frames and EPDM rubber seals.

3. Fire Protection and Corrosion Prevention Specifications

Building fire protection must comply with national and association standards, such as the 'Container House Construction Quality Acceptance Standards,' which specify 12 quantitative indicators for structural load-bearing and fire protection performance. For corrosion prevention, steel surfaces must undergo rust removal and coating treatments to ensure durability.

4. Construction and Acceptance Specifications

During construction, a quality traceability system must be established, and a comprehensive quality management system implemented. Acceptance is divided into three parts: material acceptance, factory production acceptance, and on-site installation acceptance, compared against BIM models. For a inspection lot to pass, sampling of main control items must pass, the pass rate of general items must reach over 80%, and there must be no serious defects.
