Comparison between timber piles and piles.

There are lots of materials we can use for construction foundation, such as timber piles, concrete piles and steel piles. What’s the difference between them? And finally which one would be better for us? According to the ratio of using spiral welded pipe, Sara thinks that steel products have their special advantages


First, timber piles is different from concrete or steel piles as they are naturally made instead of man-made. This means they are cheaper than concrete or steel piles. Because of thenatural characteristics of timber, the density or unit weight of timber piles is variable and highly dependent on the species, specific gravity and water content of the timber itself. Under this situation, we cannot make sure the quality when they face with the hurricane which is its shortage. Of course, it is very easy of corrosion and rust which has not long life service.
What’s more, concrete piles are both similar and different to timber piles and to steel piles. Concrete and timber piles are considered “displacement” piles. Actually, we all know that concrete piles are expensive than timber piles. However, the cost would be higher than timber piles.
Finally, steel piles made by steel would have its special advantages for human. Steel piles slide past soil particles as they are being driven instead of displacing them. Due to this corrosion resistant, steel piles can be made into any reasonable lengths since splicing is usually not an issue. Of course, they can withstand hard driving situations but unlike concrete piles are not subject to a wave, so this is the main reason to use it like other hot rolled steel pipe such as seamless steel pipe, spiral steel pipe and ERW steel pipe?
What I want to say is that when we see this building, it looks beautiful. The appearance of beautiful, of course, also including the shape of the various kinds of steel pipe, such as ERW steel pipe, spiral welded pipe, used for water, oil and gas transportation.
No matter which kind of steel pipe you choose as your project. Poor quality steel pipes will be kicked out of the group. So, how do we figure out what we need to do with precision engineering or to estimate housing? Comparison will be our first choice.
Straight seam high frequency welded pipe is welded by welding and induction welding, divided into two forms: hot rolling and cold rolling. Hot rolled coils are used as raw materials, and other processes, such as continuous forming, welding, heat treatment, sizing, straightening, etc., there is no doubt that ERW steel pipe used for low pressure liquid delivery, such as water, gas, oil, etc.
Spiral welded pipe has the characteristics of short, high dimensional precision, uniform thickness, surface quality and so on, and has higher pressure than cold galvanized steel pipe china . Therefore, when we encounter this situation, we can select the helical welded pipe of the high-pressure engineering project instead of the ERW steel pipe.
