Installation and maintenance
Retractable bollard receivers must be dug into the substrate, since the bollard body slides completely into the ground receiver. To keep bollards functioning over a long time, planning and proper installation are important.
Maintenance
Outdoor sites accumulate dust and debris over time. To ensure long-term operability it is important to schedule maintenance of manual retractable bollards into the yearly site schedule. Bollards should periodically be removed and have moving parts lubricated. The receivers should be vacuumed of debris. For detailed technical information, see the Retractable Bollard Technical Guide.
Drainage
Proper drainage is a very important requirement for the long life of raising bollards, and consultation with an engineer can provide specifics to a location. If the bollard receivers fill with standing water, it increases wear on both the bollard and the installation. Even stainless steel will begin the process of corrosion during an extended soaking, compromising the finish of the bollard, impacting the smooth operation as well as the aesthetics. The freezing expansion of standing water, in sub-zero temperatures, could severely impact the operation of the bollard, through breakage or sticking.
