In architecture a corbel is a structural piece of stone, wood or metal jutting from a wall to carry a superincumbent weight, a type of bracket.

You see corbels throughout San Francisco, and they are very common on Victorian homes. Many corbels on homes are made of wood, and as such are prone to rot over time. The corbels often have unique shapes, and we copy the shape to replace rotten corbels, and match any remaining corbels on the building.

Custom corbels are made according to the following steps:
- Wood of the proper thickness is chosen, or wood is laminated to achieve the desired thickness.
- The wood is run on the joiner, cleaning up and making smooth surfaces.
- The wood is chopped to length with a miter saw, giving two clean working ends.
- The wood is then run through the thickness planer bringing to the proper dimension.
- The outline of the old corbel is then traced onto the wood.
- The outline is cut with a bandsaw.
- The new corbel is sanded and painted as needed.

Because wood is an organic product, a wide variety of factors can affect the usability, structure, look, and strength of a given harvest. Even within a species of tree, great variations can exist. This is why lumber grading exists. Lumber grading is the process of assessing the quality and characteristic of the lumber. This way both the producer of the dimensional lumber and the builder can agree on what the product is and how it can be used.
To insure the highest level of consumer trust, and professional consistency, Channel Lumber employs the West Coast Lumber Inspection Bureau (WCLIB) to inspect and randomly pull grades to insure that Channel Lumber is shipping ongrade products.
What are the specific grades for lumber? This is a complex question, given the different species of lumber, and the diverse milled products on the market, but let’s try to simplify. Hardwoods and softwoods have different rating system. We will only be talking about softwoods here, as these are most common in general construction.
The rules for grading softwood are written by the American Lumber Standard Committee. The rules vary regionally to address local conditions of logging, etc. Softwoods are generally graded into three categories:
- Appearance (wood that will be seen, like flooring and siding).
- Factory and Shop Grades (wood for remanufactured products like doors, and window frames).
- Structural (graded from strength. Appearance is secondary or non-consideration).

Technology is transforming the lumber industry, and Resysta® is at the leading edge. At Channel Lumber we are pleased to distribute and represent this Green building product. Here are some facts about Resysta® that can help you decide if it is right for your next project.
1. Resysta® is made of agricultural waste. About 25% of this is rice husks, a renewable product in great supply.
2. Resysta® looks like wood, and be repaired and treated like wood. It can be drilled, painted, oiled and sawed, with the advantage that it does not splinter.
3. Resysta® is not susceptible to insect infestation. It is water (even saltwater) resistant, slip resistant, and has a lifespan longer than wood.
4. Resysta® comes in a variety of formats, including decking, siding, and facade.
5. Resysta® does not contribute to deforestation.
6. Resysta® is class A fire resistant, will not absorb moisture, and shows no evidence of fungal decay in tests.
7. There have been many synthetic wood products that have come and gone over the years. Although many had excellent structural attributes, they simply did not have the warmth and look of natural wood. This is where Resysta® shines. It looks and feels the woods that are most popular in design and construction.
Channel Lumber carries a variety of Resysta® products. Please contact us for more information.

The Carquinez Bridge which spans the Carquinez Strait between Vallejo and Crocket is actually two bridges. The eastbound span is a cantilever bridge completed in 1958. The westbound span is a suspension bridge completed in 2003, with Channel Lumber providing products and services throughout various phases of its construction.
The original Carquinez bridge was built in 1927, and provided for three lanes of traffic. This was the first major structure built for crossing the bay. Prior to the bridge, Carquinez Strait was navigated via ferry service six miles from the current bridge crossing.
After the Loma Prieta earthquake in 1989, the 1927 span of the bridge was surveyed and deemed no longer safe for passage. At that time traffic was consolidated on the 1958 cantilever span, while the original bridge was demolished.
The new Carquinez Bridge is outfitted with 33 wireless “nodes” which collect and transmit data about the structure. This allows engineers to monitor the bridge closely, and undertake any needed repairs efficiently. The bridge currently operates 8 lanes handling 100,000 cars per day.

In September 2015 Dolby Laboratories opened its new headquarters on Market Street in downtown San Francisco. The building was a consolidation of two separate buildings, one in Potrero Hill, one South of Market. The renovation of the former State Insurance building utilized a significant supply of fire treated Forest Stewardship Council® (FSC®) lumber provided by Channel Lumber.
Dolby Laboratories is known worldwide for creating the seminal circuit which removed unwanted noise and hiss from sound recordings. The circuit was patented in 1969 by inventor and founder Ray Dolby. The name Dolby since has become synonymous with industry leading sound production, and is used widely for sound recordings for movies, and popular music.
Several artists were commissioned in the design of the new facility, and the office transitions seamlessly from open, revolving work space to art installations, infusing the headquarters with creativity and innovation. The traditional cubicle format was abandoned to encourage employees to experiment and express themselves through their work environment.
In addition to sound production, Dolby Laboratories also features on site theaters, and a research facility which, among many, conducts experiments on how sound and media affect human physiology. Current popular releases using Dolby are too numerous to list and include “Ghost in the Shell”, and “King Arthur”.

For a group of employees who affectionately refer to themselves as “Nerds”, the employees of Nerdwallet have one of the hippest HQs in San Francisco. Located at 901 Market the company is housed in one of the most competitive, emerging commercial neighborhoods in San Francisco.
The new Nerdwallet digs can house up to 300 employees, though when they moved in they had roughly 150 employees. The feel of the office is light, with lots of comfortable, non traditional places for employees to meet and break away. Sun filled corners, all window conference rooms, bean bags, all add to this home away from home ambience.
In addition the facility features free yoga and boot camp classes, free catered lunches, and a fully stocked bar (JD81) with over 80 spirits that employees can mix and match. Oh, and of course there is a ping pong table.
Channel Lumber provided a variety of products and services for this visionary project. For more information on how Channel Lumber can help your next project, please contact us.

At Channel Lumber, sustainable building is one of our primary goals. Sustainability and “Green” building means that the process of construction, from forest growth and management, harvesting, transportation, on site materials and procedures, recycling and refuse, and the functioning of the completed facility all adhere to the highest standards of eco-sustainability.
Channel Lumber is Certified by the Forest Stewardship Council (FSC®), the United States’ highest standard for forest management and lumber products. Channel Lumber also works closely with LEED standards, which provide a framework and grading scale to help projects find the most cost effective way to build green. More information on both of these are outlined on the Green Building page of our website.
There are so many design features that can help to create more sustainable structures, and better forest management. Simple concepts— building near public transportation to minimize driving resources, positioning a building to maximize solar sun exposure and natural warming, and even building smaller. Sharing structural materials and building the foundation and roofing surface areas up instead of out are additional ways to improve environmental efficiencies. Builders can cut costs and create unique designs by reclaiming and reusing lumber and materials.
