Maple divided into soft Maple and hard Maple belongs to temperate wood species, and grows mainly in Yangtze valley ,Taiwan and East America. Maple wood is ash brown or gray red, light and hard with not-obvious annual ring, interlocked grain, fine and uniformity structure. It is easy to process.

Brief introduction

Maple belongs to aceraceae.There are more than 150 kinds of maple trees widely growing in North America, Europe, North Africa, East and central Asia. According to hardness, it is divided into two kind:hard Maple(white Maple,black Maple) and soft Maple(red Maple, silver Maple).The hard Maple is 25% harder than soft Maple.So hard Maple is more expensive than soft Maple. ACERSaccharum and A.nigmu is the most famous out of kinds of Maple wood. It is called Canada Maple because there is Maple leaf on the national flag ofCanada. Maple is an historical tree inAmericaand Europe.People use Maple ash to make soap before.In 20s, Maple is the material for making propeller.So far,Maple is also hot in making furniture,wood flooring and sports equipment.On the other hand, sap of sugar maple can be the raw material for sugar. Maple sugar is an unparalleled kind of sugar. Maple sugar section is also an traditional festival inCanada.

 Distribution

Maple widely grows inYunnan and northeast of China.The Acer mono is a kind of Maple in China.It was set wood material for spindle in textile mill and shoe tree in shoe factory. Because of origin differences and varieties differences,some Chinese Maple is soft with loose structure,not-obvious grain,low gloss which is less favorable than Maple from Europe andAmerica. However,Some Maple wood with bird’s eye grain and crouching grain is the highest grade.

Utilities

Maple ,because of its uniform color, is often made as furniture,high-class furniture, wooden shovel and paper.Its utilities including:veneer,framework of timber structure, lamps,lanterns, cabinet and turning products.

Color

Milky white to white with light reddish brown.

Feature

Uniformly dense wood, good finish performance, light green gray mineral grain,easy to paint

Manchurian Ash

Manchurian Ash，was protected as a vulnerable plant in China. It grows dispersedly and drops in number because of over cutting. Manchurian timber is hippocastanaceae with high hardness and beautiful wood grain. The trees can grow as tall as 30 meters, mainly in North China andNorth China. The wood can be made into different furniture, instrument, sports appliance,car,ship, mechanical sets and special building materials. At the same time, it is the best material for studying Arcto-Tertiary flora and the climate of Quaternary ice age.

Wood Species – Ipe

Posted on August 9, 2012 by chinafloor

 

Scientific name: Ipe

place of origin:Brazil

Characteristics: Definitely A grade timber, pure color, districted from B grade timber which is covered by dark color.12 colors were dyed to meet different requirement of customers. For its unctuous characteristic, PU coating is applied in the flame plating process with PU’s good adhesion. The PU coating is thick and heavy. With wear-resisting coating, it does great good to increase abrasive resistance.

Ipe wood is largely planted inSouth America, and called red sandalwood mistakenly. Ipe timber is hard, thick, heavy and beautiful grain& color with strong performance of erosion resistance, corrosion protection and resistance to deformation force, stability, adaption to different climates. It is most popular in home and abroad.

The various aberration of Ipe timber is supposed to be its strength but since people seek the same color of each timber, heavy painting process is applied in dyeing.

Most customers are satisfied by multi-color and natural beauty of Ipe timber. However, it is difficult to figure ou the color difference of Ipe timber for lacking of powerful business and large-scale production. Enterprises with strength are your wise choice to buy quality Ipe floors.

Normally Ipe flooring cost 300RMB per square. Of course, different brands for different prices. Price depends on different elements, like word of mouth of enterprise, raw material price, etc.

 After installation, the protecting process is more complicated than laminated floors. It should be away from large amount of water and exposing to the sun for long time. Normal heating ground is not suitable for hardwood flooring. Because natural hardwood flooring is easy to hunch-up and crack,so cautious protection should be taken.

Wood Species – Oak

Posted on August 3, 2012 by chinafloor

Oak trees

 

Geographic Distribution

Oak mainly grows in Europe and North American and largely produced fromRussiaandAmerica.

InChina, a piece of Xylosma grows inJilin,Liaoning,ShanxiandHubeiprovince, is similar with Oak on wood character. So two type of wood species are called Oak in English. There is large number of Oak trees inJilin,Liaoningand a few in Shennongjia of Hubei before. Because of the short diameter of Oak, lack of specialized production process and band on exportation, few oak timber is sold to other countries. Oak wood of primer grade is normally imported from other countries which cost nearly 10 thousand yuan per cube.This is reason that oak furniture is on a high price.

The advantages and disadvantages of oak wood

The advantages of oak wood

  1. Clear mountain grain, elegant and a nice touch
  2. Excellent workability, can be bended.
  3. Good hardness and long-term service
  4. High class and suitable for making furniture of Eurpopean style and classic style.
  5. High density ,not easy to absorb water, corrosion resistance, high strength

The disadvantages of oak wood

1) It is hard to find high-quality species, mostly imported fromRussiaandUnited States, but also some imported fromTurkey,Austria,GermanyandCanada. Few also produced in Europe andAfrica.

2) Oak timber imported from foreign country after strict drying process and has good performance of stability. Some manufacturers directly import Oak logs from other countries and finish drying by themselves. Local Oak wood furniture and flooring has a good performance of stability, but since it is hard to dry off all water from Oak timber, we may see deformation or shrinkage after being used by years.

3)It is normal to see many Oak substitution in market.If customers are not lacking of professional knowledge, it is easy to buy fake oak wood.

Its heartwood is yellowish-brown color shading with slight red and then turns into slight brown or light yellow-green when we look at its sapwood. With its unique leather-like smell, people are easy to recognize teak wood and get a fatty flu.

The most valuable character is corrosion-proof and excellent performance of teak timber. It takes Burma Teak and Thailand Teak as the best. But since Teak exportation has been prohibited inThailand, so the Burma Teak gets hotter for importing.

High density and hardness, corrosion resistance are the tropical label for teak wood. In Europea, people use teak wood to make yachts and so does their deck, other historical cathedrals and old buildings. Even the beautiful buildings at Shanghai Bund– the most prosperous areas inChina,are made of teak.

Teak is of great value, which takes 50 years to grow into lumber. In natural environment, the most productive forest district can plant 1-5 teak trees per mu. The most miraculous thing is that color of dressed side gradual change into golden yellow under photosynthesis processing.

Characteristics of Teak Timber

  1. heavily oleaginous, defend snakes, mosquitoes, ants and insects
  2. golden yellow surface conducted by photosynthesis, the longer the prettier
  3. unique natural fragrant and depressant for nerve
  4. high density and hardness, uneasy to twist and abrade
  5. unfinished and prefinished board can be used
