Now the common spool mainly have: stainless steel spool, copper spool and ceramic spool three. Stainless steel spool is currently a high-tech faucet spool, but if the stainless steel material is not pass, then it is easy to rust on the water quality caused by pollution. Copper spool is the heaviest and more expensive kind of spool, the same high quality requirements for copper, otherwise it is easy to accumulate scale. Ceramic spool is the best spool, with strong abrasion resistance, good sealing, long service life and high temperature resistance, etc., get a lot of high-quality products are widely used. Like the American Standard imported ceramic spool is fired at temperatures up to 1400 degrees Celsius polished and become durable. Now common spool mainly have: stainless steel spool, copper spool and ceramic spool three. Stainless steel spool is currently a high-tech faucet spool, but if the stainless steel material is not off, then it is easy to rust on the water quality caused by pollution. Copper spool is the most heavy and more expensive kind of spool, the same quality requirements of copper is very high, otherwise it is easy to accumulate limescale.
