Perforated channel connectors are used to extend channel length.

To ensure corrosion protection, the following types of coating are applied:

• SZ – preliminary galvanizing using Sendzimir process, with class Z140 or higher (as per GOST R 52246-2016)
• SZ270 – preliminary galvanizing using Sendzimir process, with class Z275 or higher (as per GOST R 52246-2016)
• RAL – polymeric powder coating of a steel product preliminary galvanized using Sendzimir process, with class Z140 or higher (as per GOST R 52246-2016)
• HDZ – hot-dip galvanizing of a finished product (as per GOST 9.307-89)
• INOX – stainless steel (AISI304)
• INOX316 – stainless steel (AISI316)
