At Doity, every mezzanine floor is engineered to meet precise performance, safety, and compliance standards. Below is an overview of the key structural and material specifications we work with.
Structural Design & Load Capacity
Design Load Range: 3.5 kN/m² (light duty office) up to 10 kN/m²+ (heavy industrial).
Column Spacing: Typically 3.0 – 6.0 metres (custom layouts available for machinery or racking).
Beam Spans: Up to 8 metres depending on section size and deflection limits.
Deflection Criteria: L/250 (standard) or to project-specific requirements.
Structural Codes: Designed in accordance with BS EN 1993-1-1 (Eurocode 3) and BS 5950 for structural steelwork.
Materials & Components
Primary Steelwork: Cold-rolled galvanised C-sections.
Secondary Joists / Purlins: Cold-rolled galvanised C-sections or RHS members.
Decking Options:
– 38 mm particle board (standard industrial)
– Heavy-duty OSB or durbar plate (for higher point loads)
– Open-mesh grating (for airflow or sprinkler access)
Column Baseplates: Engineered to suit slab thickness and load dispersion.
Safety & Compliance
Fire Protection: Fire-rated ceilings, column casings, and fascia systems available for 30/60/90-minute protection.
Guardrails & Handrails: To BS 6180 standards.
Staircases: Designed to Building Regulations Part K (and Part M where applicable for access).
Load Testing & Certification: Full structural calculations and compliance documentation supplied.
Integration & Services
Mezzanine structures can incorporate:
– Conveyor and goods-lift interfaces
– Catwalks and access platforms
– Integrated lighting and sprinkler systems
– Electrical and data containment
CAD drawings and 3D models are provided for coordination with existing building layouts.
