Product Overview

The MT-42 profile by Hiansa is a metal roofing and facade profile characterized by a 42 mm rib height, providing strong resistance suitable for a wide range of spans. It is manufactured in steel thicknesses from 0.50 mm to 1.20 mm, with a useful width of 1000 mm and lengths typically ranging from 1,600 mm to 14,000 mm. The profile is available in galvanized or prelacquered finishes with a broad color range according to Hiansa's color chart. Optional perforations (3 mm diameter, 5 mm spacing, 60º staggered) can be supplied for specific mounting solutions.

Geometric Characteristics and Material

Applications

The MT-42 profile is suitable for various applications including:

• Sandwich panel roofing (interior and exterior profiles)
• Deck roofing
• Simple and sandwich facades (interior and exterior profiles)
• Lost formwork
• False ceilings

Standards and Norms

The product complies with the following standards:

• EN 508-1: Self-supporting steel sheet products for roofing and cladding
• UNE 10143: Hot-dip galvanized steel sheet and strip dimensional and shape tolerances
• UNE 10346: Continuously organic coated steel products
• UNE 14782: Self-supporting metal sheets for roofing and cladding
• Steel grades conform to S220GD to S320GD with an elastic limit of 220 N/mm²
• Fire reaction classification: Class A1
• Water permeability and emissions meet regulatory requirements

Structural Performance and Load Tables

Load tables provide allowable uniformly distributed service loads (kg/m²) based on span length and steel thickness, calculated according to Spanish standard NBE EA-95. The tables ensure compliance with ultimate limit states for normal and shear stresses and serviceability limit states with deformation limited to L/200.

Roofing Load Capacities

Tables are provided for 1, 2, and 3-span conditions, showing allowable loads for thicknesses from 0.50 mm to 1.20 mm and spans from 1 m to 3 m. Two profile faces (A and B) have different load capacities, with face A generally supporting higher loads.

Facade Load Capacities

Similar tables are provided for facade applications under 1, 2, and 3-span conditions, with allowable loads varying by thickness, span, and profile face.

Key Recommendations and Limitations

• Profile thickness selection should consider span and load requirements.
• Length tolerances and dimensional deviations must be respected for proper installation.
• Perforations are optional and should be specified if required for mounting.
• Compliance with fire and environmental standards is ensured.
• Hiansa reserves the right to modify specifications without prior notice.
