25 years of generation — isn`t an every day task for SPP! The expert on designing and assembling with good professional practice more than 7 years in this area will say about it:
- What kind of steel should be used for building of SPP according to DBN of Ukraine.
- How to understand the steel grade?
- The kinds of anticorrosive coating of metal and what is the difference between them?
- What is included into the cost of iron assembling?
- How we can take care of SPP made by iron for prolongation of service lifetime?
- How does corrosion appear on iron?
- How zinc covering defends steel from corrosion?
- What is galvanic couple?
- How is the fastener system from zinc plated?
- The oval and circular holes should be in profile and why.
- The fastener system- to -system comparison from zinc plated steel and constructions from iron. .
- Why in Europe there is an assembling of SPP without aluminum plates?
- Do you need design calculations for building of solar electric plant?
- What are the norms of DBN of Ukraine should be the fastener systems for SPP meet?
The fastenings of Solar Stalconstrukciya exclusively are produced from structural steel: S235JR, S350GD. Where 235 and 350 are hardness indexes and a consequence — dimensional stability.
Our company offers 2 kinds of covering:
—the roll zinc-coating in thickness 25 microns (it is also named as cold zinc).
—the zinc-coating of end product in thickness 50 microns (it is also named as hot-dip zinc coating).
The zinc coated steel (or cold zinc) — is a covering of metal by layer of zinc in defense of corrosion. The not protected steel oxidizes in the air. That`s what rust collects.
If we cover the steel by layer of zinc, its protecting film will not allow to pass the oxygen to wash metal and ferrum that is under the cover. Thus, the iron will be protected from corrosion.
The zinc and iron make galvanic couple, wherein the steel — is less active metal, resulting from the zinc enteres into reactions of corrosion by first and the base metal remains nearly untouched.
The fastenings of proprietary design of Solar Stalconstrukciya are universally applicable. It is quick and easy for assembling. And it does not require any additional equipment and finishing.
Please be aware that holes in profile have exactly oval shape. What has been done in response to the difference of material property of aluminum and steel. It expands with different strength and intencity. If it is not done the glass flat of panel will crack.
Thus, the iron is cheaper than our zinc-coating design concepts, before it is not prepared in no way and already drilled in place. And hole configuration will never be oval.
Our staff — competent engineers, who previously make all necessary calculations under each project. So that rarely if ever you can see at assembly.
