Multi-Unit Prefabricated Steel Dormitory Building For Group Staff Collective Living

Multi-Unit Prefabricated Steel Dormitory Building For Group Staff Collective Living

Product Description

This multi-unit prefabricated steel dormitory is purpose-built for staff collective accommodation, widely adopted for factory campuses, construction bases, mining zones and project camps. The main structure is a lightweight portal steel frame system. Wall and roof adopt insulated sandwich panels, delivering thermal insulation, sound insulation and waterproof performance. Independent divided rooms, public corridor, restroom and kitchen area can be reasonably arranged. All steel components and panels are prefabricated in the factory, with fast on-site assembly, clean construction site and short occupancy cycle. The whole building has neat appearance, flexible layout and comfortable indoor environment to satisfy long-term centralized living demands of employees.

Compliance, Certifications & Standards

Our steel dormitory complies with ISO 9001 quality management system. Structural design follows GB, Eurocode or ASCE standards as requested. We can provide CE EN1090, SGS inspection reports, MTC material certificates and fire test reports for cladding panels. All materials and structural schemes meet local building codes for temporary or permanent residential buildings.

Customization Service

We support full personalized customization. Room quantity, single room size, floor height and total floors can be adjusted. You may choose panel material, thickness, door & window style, interior partition, power circuit and plumbing layout. We tailor the plan according to your site space, number of residents and local climate condition. Extra options include sunshade, balcony, security window and public activity area.

Cost & Quotation

The final price depends on floor quantity, building size, steel grade, panel specification, interior finishing standard, load parameters and delivery scope. We provide itemized formal quotation with clear breakdown of steel frame, cladding panels, fittings, accessories, design fee and shipping cost. No hidden charges. Once the design scheme is confirmed, the quotation remains stable within agreed validity period. We balance quality and budget to offer economical housing solutions.

After-sales Guarantee System

We supply complete installation manuals and technical guidance. Our engineers offer remote video support during erection. We provide long-term technical consultation for structure maintenance, panel replacement and fitting renewal. Spare parts can be supplied at preferential price. We track project feedback actively and respond to your technical inquiries promptly.

Seismic & Fire Protection System

The steel frame adopts bolted connection with reasonable bracing layout for good ductility and seismic resistance, adaptable to different seismic acceleration zones. For fire safety, rock wool fire-rated sandwich panels are optional. Fire separation partitions, fire doors and smoke vent settings can be arranged. The system controls flame spread and protects residents.

Service Life of Steel Structure

With standard Sa2.5 blasting and qualified anti-corrosion coating treatment, the design service life reaches 50 years for permanent use. For temporary camp dormitories, the usable life can reach 15–20 years under regular maintenance.

Technical Parameters

Design dead load and live load follow residential building requirements. Standard single room size: 3m×6m / 3.6m×7.2m; normally 1–3 floors. Main frame steel: Q355B; purlins and secondary members: Q235B. Surface treatment: Sa2.5 blasting + anti-corrosion paint or hot-dip galvanizing. Sandwich panel thickness: 50–100 mm. Wind load and snow load are calculated based on local site conditions.
