Why ERW steel pipe pile used widely and How to Keep

Do you know the top reasons why straight-seam ERW Pipe piles used widely in projects?
Here you will get the idea.
1st. Green and Sustainable— Steel’s high recycled content and high reclamation rate make it the ideal material for green structures. 
2nd. Equal Weight Distribution —The cylindrical shape of straight-seam piles distributes load equally, compared to H-piles.
3rd. Superior Load Bearing —With 30% less weld per foot than spiral-weld, straight-seam ERW pipe piles are less likely to experience weld failure, making them the preferred choice for load bearing and structural support applications.
4th Easier Splicing — Based on market feedback, we know it takes less fit-up time to splice straight-seam piles compared to spiral-weld. Spiral-weld piles can unravel when spliced and the outside bead needs to be filed down for mechanical coupling. Straight-seam piles keep projects moving on time and within budget.

Besides the above merits, how to store it.
Here 4 Ways to provide.
1. choose the appropriate venue and warehouse 
2. reasonable stacking, advanced first release 
3. protective material packaging and protective layer steel factory pre-coating preservatives or other coating and packaging, which is an important measure to prevent material corrosion, in the process of transport handling must pay attention to protection, can not be damaged, can extend the storage of materials the term 
4. keep the warehouse clean, strengthen the material conservation
