Panel Specifications
The document provides detailed specifications for the ALUSTEP® 500 SL sandwich panel. The total thickness of the panels ranges from 5 mm to 20 mm, with skin thickness consistently at 0.3 mm + 0.3 mm. The core thickness varies from 4 mm to 19 mm, and the weight ranges from approximately 1.79 kg/m² to 2.63 kg/m².

Core Composition
The core is made of aluminium honeycomb from the 3000 alloy series, featuring hexagonal cells with diameters of Ø1/4” and Ø3/8”. The foil thickness ranges from 50 to 70 microns, with a thickness tolerance of ±0.3 mm and dimension tolerance of ±30 mm. The panel's weight is specified as 56 kg/m³ for Ø1/4”.

Skin Composition
The skins are made of bidirectional glass fiber fabric, weighing 490 g/m² and impregnated with epoxy resin. The aluminium alloy types used are 3003, 3005, 3103, and 3104.

Honeycomb Core Properties
The honeycomb core properties include a density range of 56-59 kg/m³ for Ø1/4” and 39-40 kg/m³ for Ø3/8”. The compressive stabilized strength is 3.0-3.5 MPa for Ø1/4” and 1.4-1.95 MPa for Ø3/8”. For a thicker foil of 70 microns, the density is 80-83 kg/m³ for Ø1/4” and 54 kg/m³ for Ø3/8”, with compressive strength of 4.3-4.6 MPa and 2.5-2.6 MPa respectively.

Standard Dimensions
The standard dimensions of the panels are 3000 mm x 1500 mm, 3000 mm x 1250 mm, and 2500 mm x 1250 mm, with a dimension tolerance of ±30 mm.
