Technical Information
RIGIDITY
RAYBOND and its affiliated products are highly rigid compared to solid metal sheets. When pressure works on RAYBOND panel, two sheets of metal skin behave like a strong H-section.
Rigidity of RAYBOND in comparison with other materials of the equivalent rigidity
| RAYBOND and its affiliated products | Solid metals of the equivalent rigidity | |||||
| Aluminum Specific gravity: 2.71 E: 70×103 MPa or N/mm2 |
Stainless steel (304) Specific gravity: 7.89 E: 190×103 MPa or N/mm2 |

LIGHTWEIGHT
As RAYBOND and its affiliated products are composite materials that is composed of metal skins and the core material, their weights are lower than solid metal sheets of the same rigidity. The following table shows RAYBOND products’ weight versus typical building materials.
RAYBOND and its affiliated materials
| Material | Thickness | Specific Gravity | Weight kg/m2 |
| RAYBOND A2 | 4mm | 2.03 | 8.1 |
| 3mm | 1.99 | 6.0 | |
| RAYBOND/FR | 4mm | 1.90 | 7.6 |
| 6mm | 1.81 | 10.9 |

| Acrylic sheet | 4mm | 1.2 | 4.8 |
| Gypsum board | 12.5mm | 0.86 | 10.8 |
FLATNESS
RAYBOND and its affiliated products are very flat due to usage of ALLOY 5005 aluminum coil, compared to solid metal sheets. Solid aluminum sheet, for example, has a slight distortion stemming from its rolling process: buckles, edge waves and overall warping are common. RAYBOND’s flatness stems from the laminating process in production in which most of such distortions are eliminated.
FIRE SAFETY
RAYBOND/fr is a fire-safe material, passing mandatory requirements for exterior and interior in most countries. Though the core material does contain a small amount of combustible polyethylene, the main ingredient of the mineral does not permit the proliferation of flame and restricts the development of the smoke detrimental to the evacuation activities. RAYBOND™, on the other hand, is composed of two skins of aluminum that prevents fast spread of fire frame. RAYBOND and its affiliated products pass the following fire tests.
