How to distinguish between hardwood and wood
Hardwood is not easy to carry out anti-corrosion it some hardwood itself has a natural anti-corrosion properties such as pineapple grid
Hardwood categories: rice eucalyptus, pineapple grid, gold grapefruit and other imported wood.
Pine wood: pine wood (red pine), carbonized wood, carved wood, firewood, camphor pine, southern pine, Douglas fir, red cedar, radiant pine, hemlock and so on a series of preservative wood. No carving, texture clear, delicate lines. With a rosin flavor, a beautiful scar. Production process requires high, need to dry degreasing.
Hardwood antiseptic wood generally higher than the pine wood density, pattern is also different from the common outdoor hardwood antiseptic wood pineapple grid, Baro wood, rice and other eucalyptus.
And pine generally have their own unique patterns, commonly used are Pinus sylvestris, southern pine, pine, radiation pine, red cedar, etc.
Pine and hardwood are the difference between trees
Hardwood density, natural anti-corrosion performance is better, most of the color was red and yellow, easy to accept high-end people, and not easy to crack, deformation, no oil. As the hardwood material are taken from the heart material part, the density is large, it is more difficult to carry out anti-corrosion treatment, and do after the anti-corrosion products, the surface color will become bleak, so usually do not need to do anti-corrosion treatment. So relatively more environmentally friendly, the price is relatively high.
Therefore, if you consider the cost, recommend conventional pine wood preservative wood, the use of high-end places is recommended in the use of hardwood.
Choose the right material according to the purpose and price.
In addition, in the easy to suffer termites and salinity high places, it is recommended to use relatively high permeability of the South American pine.
