Lederer, a stainless steel fastener and screw nut expert, published the latest style of the company. 4 different styles are in line with French NFE 25-514 standard, produced in A2 stainless steel, size M3-M24.
Z models / M models / L models / LL models can be distinguished from the difference between the inner and outer diameters, and have a minimum hardness of 150 HV according to the French standard (compared to DIN, such as DIN 125, the minimum hardness of 140HV). Some individual sizes of Z (M5, 10, 12 and 16) and LL (M16) have the same dimensions as DIN 125 (Z) and 9021 (LL). As for other styles, the difference is not big.

Colour Laminated Glass is very similar to Clear Laminated Glass but with the addition of a coloured interlayer. These allow for a rich palette of colour permutation, ranging from subtle transparent and translucent colours to opaque. Our colour laminates are manufactured using float glass as standard although also available in specialist glasses including low iron (crystal clear) and a variety of body tints (blue, bronze and grey). The type and thickness of the glass will have an effect on the colour chosen.
Laminated glass is produced when two or more glass lites are permanently bonded with one or more plastic interlayers (PVB) using heat and pressure. The glass and interlayers can be a variety of colors and thicknesses. Laminated glass is often called [safety glass" because it meets the requirements of various code organizations. Laminated glass can be broken, but the fragments tend to adhere to the plastic layer and remain largely intact, reducing the risk of injury. Laminated glass can be incorporated with heat-strengthened and Tempered Glass to further increase impact resistance.
It can be made into clear laminated glass, colored laminated glass, Triple Laminated Glass, laminated Insulated Glass , printed laminated glass, Low-E Laminated Glass, toughened laminated glass, tempered laminated glass and so on. Colored laminated glass can be reach by colored PVB, color tinted glass, and also printed laminated glass, depend on customer's design request.
