Guinea Correctional Double-Level Steel Bunk Bed Project | Zehao
By ZEHAO FURNITURE
1. Project Overview
Zehao Furniture is a Chinese steel furniture manufacturer specialising in heavy-duty bunk beds and dormitory furniture for government, institutional and commercial projects. This case study covers a 2024 correctional facility furniture supply programme for Guinea, West Africa.
The project involved the manufacture and export of 1,500 double-level steel bunk beds for ENIGMA SARL, delivered to Conakry, Guinea. The order was confirmed under PI ref. 24LTH12620-01 in September 2024. Production followed an approved pre-production sample, and the full shipment was containerised and exported in November 2024.
Overall bed dimension: 1900 mm(L) × 900 mm(W) × 1750 mm(H)
Per-bed net weight: 45–46 kg
Load capacity: 400 kg per bed
2. Client & Procurement Background
The buyer is a Guinean company supplying institutional furniture to correctional and dormitory projects in Conakry, Guinea. The requirement was for a robust, high-density sleeping solution that could be fixed to floors or walls for anti-tip safety.
- Client type: Institutional / correctional project buyer.
- End user: Correctional facility dormitory, Conakry, Guinea.
- Procurement reference: PI 24LTH12620-01 (September 2024).
- Payment terms: Telegraphic transfer advance + balance before shipment.
- Quality requirement: Pre-production sample approval before mass production; buyer inspection rights during production and before container loading.
3. Technical Specification — Double Bunk Bed 24LTH12620-01 (Correctional Grade)
The double bunk bed was engineered for high-density correctional environments. Every specification below was extracted from the signed technical sheet and sample approval record.
- Overall size: 1900 × 900 × 1750 mm (L × W × H)
- Posts: Φ48 × 2.0 mm round steel tube
- Side rails: 25 × 50 × 1.0 mm rectangular steel tube
- Bed deck supports: 20 × 20 × 0.8 mm tube × 7 bars
- Ladder and guard rails: Φ19 × 0.9 mm round steel tube
- Bed base: Φ3.8 mm steel wire mesh deck (ventilated, no timber components)
- Lower bed height from floor: approximately 400 mm
- Spacing between sleeping levels: approximately 950 mm
- Anti-tip safety: 4 fixing plates included; beds can be anchored to floor or wall with 4–6 fasteners
- Finish: Silver-grey anti-rust coating
- Assembly: KD flat-pack; bolt-together frame
- Net weight: 45–46 kg per unit
- Load capacity: 400 kg per bed
4. Why Steel Wire Mesh Decks for Correctional Use
The Guinea specification used a steel wire mesh base rather than plywood. For correctional and high-traffic dormitory environments this delivers three practical advantages:
- No timber components: eliminates concerns about splintering, moisture damage or pest infestation in tropical climates.
- Ventilation: open mesh allows airflow under the mattress, reducing heat and moisture build-up.
- Inspection-friendly: mesh construction does not create concealed cavities, simplifying security checks in institutional settings.
5. Quality Assurance & Sample Approval
Before mass production, one complete sample bed was manufactured and submitted for buyer approval. The approved sample became the production standard. Quality controls during the order included:
- Pre-production sample approval before raw material batch release.
- Dimensional verification during assembly.
- Buyer right to inspect production and final goods before container loading.
- Flat-pack packing inspection to confirm container utilisation and part protection.
6. Logistics & Delivery
The full order of 1,500 beds was flat-packed and shipped from China to Conakry, Guinea. Container loading was optimised to 250 units per 40-foot high-cube container.
- Origin: Shengfang / Tianjin area, China
- Port of discharge: Conakry, Guinea
- Vessel reference: MSC RUBY / FY445A
- Export declaration date: 9 November 2024
- Total quantity: 1,500 double bunk beds
- Container plan: 6 × 40 HQ containers, approximately 250 beds per container
- Total gross weight: approximately 69,000 kg
- Packing: KD flat-pack in woven/plastic bags to maximise container volume and reduce freight cost
The KD flat-pack design reduced shipping volume significantly compared with fully assembled beds, while the woven bag outer layer protected frames during sea freight and port handling.
7. Project Outcome
The order was produced and shipped within the contractual schedule. Key performance indicators:
- Order quantity: 1,500 double-level steel bunk beds
- Sample turnaround: pre-production sample approved before mass production
- Production window: within 45 days of payment confirmation
- Container loading: 6 × 40 HQ containers
- Delivery: sea freight to Conakry, Guinea, export completed November 2024
- Specification compliance: produced to approved sample and signed technical sheet
8. Frequently Asked Questions
What is a double-level steel bunk bed for correctional facilities?
A double-level steel bunk bed provides two stacked sleeping spaces in a single footprint. The Guinea project beds measure 1900 × 900 × 1750 mm, with the lower deck approximately 400 mm from the floor and the upper deck approximately 950 mm above it.
What steel specification is used for heavy-duty prison bunk beds?
The main posts are Φ48 × 2.0 mm round steel tube, side rails are 25 × 50 × 1.0 mm rectangular tube, and the ladder and guard rails are Φ19 × 0.9 mm round tube. Each unit has a net weight of 45–46 kg and a 400 kg load capacity.
Can the beds be anchored to the floor or wall?
Yes. Each bed includes 4 anti-tip fixing plates and can be secured with 4–6 fasteners to the floor or wall, meeting institutional anti-tip safety requirements.
What type of bed base is used, and why?
The Guinea beds use a Φ3.8 mm steel wire mesh base. Wire mesh is preferred in correctional and tropical environments because it contains no timber, allows ventilation and does not create concealed spaces.
What is the lead time for 1,000+ bunk beds?
For this Guinea order, production and shipment were completed within a 45-day window after payment confirmation, following pre-production sample approval.
Do you support custom dimensions, colours or specifications?

Is a pre-production sample required before mass production?
For institutional orders we recommend a pre-production sample. The Guinea project sample was manufactured, inspected and approved before the 1,500-unit mass production run.
What is the MOQ for heavy-duty steel bunk beds?
Standard MOQ is 50 pieces with mixed models acceptable. Large institutional orders such as this 1,500-unit project are produced with dedicated production scheduling and container loading plans.
