How is pressure treated lumber different from regular lumber?
Pressure treated timber is timber impregnated with chromated copper arsenate under pressure and vacuum cycles. These preserve the timber from various fungicides that would normally eat the timber reducing its life-span.
What is the cantilevered section of a deck?
under the deck there will be a supporting beam, anything hanging out beyond this beam is the cantilever. some decks are fully cantilevered (they are attached to floor joists in the house and have no support posts/beams under them). these are usually no more than 4 feet long.
How do you tanalise timber?
Timber is 'TANALISED' (treated) in an industrial treatment vessel using TANALITH preservative applied using vacuum pressure technology. TANALITH and TANALISED are registered trade marks of the preservative manufacturer, Arch Timber Protection, and may only be used to describe industrial timber treatment using TANALITH preservative. The treatment process consists of 5 stages: 1. Timber is loaded into the treatment vessel. An initial vacuum is applied, and the timber cells are evacuated of air. This vacuum is held. 2. The cylinder is flooded under vacuum with TANALITH wood preservative. 3. Hydraulic pressure is applied, forcing the preservative deep into the structure of the timber. 4. A final vacuum extracts excess preservative solution, which is then pumped back into storage. 5. Low pressure inside timber draws in surface solution when vented to atmosphere. The treated timber is then left to dry - a minimum holding time of 48 hours is recommended. In Europe, TANALITH E preservative is used, which contains copper and triazole biocides, which are commonly used to protect food crops. TANALISED E pressure treated timber can be used in a range of applications, from construction timbers through to heavy duty, highway fencing applications, where a desired service life of 15 years plus can reasonably be expected. Note that where TANALISED treated timber is cross cut, notched or bored following treatment, liberal coating of ENSELE end grain preservative is required to maintain the integrity of the preservative system. Further information on TANALITH E and the treatment process can be found on the Arch Timber Protection website at www.archtp.com. General information regarding timber treatments is available on the Wikipedia site: http://en.wikipedia.org/wiki/wood_preservation
WHAT ARE THE TYPE OF FOUNDATION?
The type of mat foundations include flat plate mat, plate thickened under columns, and two-way beam and slab. The other types are plate with pedestal, rigid frame mat, and piled raft.
Can you build a greenhouse on top of a building?
Sure, so long as the roof is structurally sound and the greenhouse isn't too big.You'll want to place it over a main beam or in an area that has walls under it to support the extra weight...or you'll have to add extra beams under it.You should get an engineer to look at it first. The building inspectors will probably want to see a plan with an engineers stamp on it anyway.
1 Describe with the aid of sketches the behavior of beams and columns under load?
the beam will sag downwads
What hazards do cast iron facades pose to firefighters?
Cast iron was used a lot in the past for building materials. Even though it is not used now for beams and columns in construction, it was in older buildings. When under high heat, and especially when under high heat and then suddenly cooled (as with a fire hose) cast iron can become extremely brittle and collapse, resulting in injury or death to firefighters. If firefighters are fighting a fire in an older building, this is a huge safety concern. Load-bearing beams or columns made from cast iron have been sited for building collapses in the past during fires.
What if your 1989 F150 has high beams but no low beams why?
is a switch to change to low beam is located under the emergency brake
What is an under reinforced beam?
Under reinforced is that in which provided steel ratio is less than balanced steel ratio. Concrete beams are designed as under reinforced beams. The reason is that the failure start by yielding of steel instead of crushing of concrete. Mian Yaqoob
What is Kiln Dried Timber?
This is timber that has been dried in a kiln (large heated structure) instead of being dried outside under cover.

How does boron react to water?
Under normal circumstances boron does not react with water.
Why are forests under threat?
The main reason why forests are under threat is because of logging. Logging is where Loggers cut down trees for timber, they then take the timber away and uses it for makig tables, chairs, etc.
Why wont the Low beams work on your 2003 impala the high beams work and also the parking lights?
you blew out a fuse under the hood just change it and it should work
How does nickel react with water?
Nickel Doesn't react with water under normal conditions
Why do you need to line up the decimal points when subtracting?
It is not a matter of aligning the decimal points, but aligning the place value columns so that the ones are under each other, the tens are under each other, the tenths are under each other, etc which is the proper way to subtract. As the decimal points are between the ones and tenths columns, with those place value columns aligned, the decimal points are aligned.Aligning the decimal points is an easy way to remember to align the place value columns, as with the decimal points aligned all the place value columns are automatically aligned.
Why do the high beams work but the low beams do not on your 1998 gmc?
I'm not sure if it is the same on a 98 as an 04. But on an 04 there is a relay box under the hood that has a relay for high beams and a relay for low beams. On an 04, it is on the driver's side behind the battery. You can check the relay by popping it out and exchanging it with another one that is working. Hope this helps
