In gardens there often is a need for fall protection devices and hand rails. In that context even plant troughs can be framed with railings. According to DIN 18065 for stairs and railings and according to local regulations like the Landesbauordnungen (LBO) in Germany there have to be fall protection devices for any height over 1.0 m (≈ 3.28 ft). That also applies to raised beds higher than 90 cm (≈ 35.43 in), that are used as a fall protection device.
For many years we have offered plug-in railing elements with round posts, made from stainless steel, system BUNIA. In the private area this system works perfectly as it can mostly be installed easily and without a need for welding parts.
In the public sector, however, the requirements concerning stability and stiffness are much higher, leading to the development of our system LAVAL. The typical surfaces of these posts are corten steel or stainless steel. The handrail, however, is always sanded stainless steel.
