Please pay attention to the distinction between completely different. The mahogany English named "ROSEWOOD", literally translated as "rosewood". The production of mahogany plants Papilionaceae, Caesalpinia, Diospyros angiosperms, and mahogany air dry density is generally greater than 1000KG/M3, sink into the water. "REDWOOD" is a gymnosperm, wood light, dry gas is about 450KG/M3, less than half of the majority of rosewood air dry density.
California Redwood brief introduction
California mahogany, or coastal redwoods, mainly distributed in California and the United States can grow up to 112 meters high, is one of the tallest plants in the world long. The oldest known rosewood was about 2200 years old.

California Redwood data Stratosphere Giant
- fourth known high surviving tree - 112.83 meters, measured in 2004. Dyerville Giant
- the history of the highest tree since 113.4 meters, fall 1991.
A claim to have 115.8 meters of trees were felled in 1912.
In addition to the tallest tree in California (Douglas Song), Douglas fir rosewood outside 100.3 meters.
According to the 2004 published in "science" magazine estimated that any tree theoretical height limit is 122 to 130 meters. At this height above the trees will because of gravity and friction effect of water diversion to the top of the tree.
hyperion (Hyperion) - the highest known surviving tree, in order to prevent visitors cause interference, location privacy - high 115.61m, diameter 4.63m, discovered in 2006.
California Redwood Characteristic
 durable, durable
The characteristics of corrosion proof, mothproof rosewood heartwood natural good, is rarely seen in the general wood processing, so how can not affect the above characteristics.
Easy processing 
Due to unique characteristics and mahogany wood grain, the mahogany easy processing, sawing, drilling, or whatever nail forming saw are very simple, general tools
High stability 
Rosewood is all American commercial wood in wood with minimal shrinkage.
All of the structure for the wood building, rosewood is the lightest weight species, 12% water content per cubic foot, weighs only 28 pounds, while its relative strength is very strong.
[good] refractory nature
The main reason of excellent properties of refractory rosewood, rosewood in the resin containing trace, can help burn even on fire, burning rate is very slow. Once the charred layer 1, which will continue to block the speed of combustion.
[cold] heat insulation, good performance
The red light wood, low density, the dried mahogany tablets become excellent conductors, such as wall plate, insulation is good.
Strong acid and alkaline resistance 
In different strength, good acid and alkali resistance properties of mahogany. Because of this property, coupled with its stability, durability, advanced materials are used as cooling tower mahogany.
Paint [especially good surface, green]
Good paint of rosewood, making it easy to combine with paint and lasting, and make easy to reduce or affect rosewood from climate and damaged, no other wood can match.
[a nail strong]
The United States Department of agriculture report experiments, the mahogany column species and one of the strongest nail for. But "DK" on the book "Carpenter" Sequoia introduced as "the nail cannot be fixed"
California Redwood Rosewood grading

B /Heart B heartwood
The heartwood of the economy, but the live section contains a certain quantity of this class is to grade, side and side plate as the standard. General wood planing, unplaned, kiln and kiln without different choices.
Use: wooden logs, siding, receiving sapwood, signs, cabinet, board and other building materials, such as high terrace, garden shelter and outdoor ground. The construction of heartwood Construction & Deck heartwood level terrace Heart
This is not a live section size and a tiny percentage of defective materials, materials are planed and unplaned two. The terrace construction is very close to the sapwood and heartwood in appearance, and are based on the strength of the classification standard.
Use: terrace, pillars, walls and fences, timber, garden and other outdoor staircase pedal for or close to the ground.
