Sun,wind or rain makes steel easily rust.
anti-rust package is necessary for customers who don’t accept rust material.
Mill standard pacakge:oiled and wrapped in pvc cloth.
With putting 2 tags per bundle and customer’s name with size on pvc cloth,you will find your material easily on port.
Shipment:bulk vessel and containers.
Established in year 2009,Bossen specializes in various kinds of steel pipes and steel concerned building materials. With an experienced, dynamic and high efficient team, our products are well-received worldwide.
We have our own factory–Tianjin Youyong Steel Pipe Co.,Ltd,which is a specialized enterprise for manufacturing longitudinal ERW steel pipe and galvanized steel pipe. The factory invests RMB150,000,000 yuan in total, covers an area of 110,000 square meters and owns more than 500 employees at present, including more than 50 main managerial personnel and production technical personnel.
Our factory now has 8 longitudinal ERW steel pipe production lines and 5 galvanizing production lines and it is capable of producing 300,000 metric tons of longitudinal ERW steel pipe a year and 200,000 metric tons of galvanized steel pipe a year.
Our factory has advanced pipe manufacturing production line, perfect inspection equipment and strictly specified quality assurance system. The company has obtained Certificate of ISO9001:2000 International Quality System and BV Certificate, etc.
A Cell is a basic unit of structure and Function of life.
1.Cells are the smallest and functional unit of life.
2.All organism are composed of cells.
3.All cells come only from pre- existing cells.
4.Cells carry genetic information in the form of DNA.
CELLS ARE OF DIFFERENT SIZE AND SHAPES
COMPONENTS OF CELL
1.PLASMA MEMBRANE:The plasma membrane, the flexible boundary between the cell and its environment, allows a steady supply of nutrient to come into a cell no matter what the external conditions are. Too much of any of these nutrients or substances can be harmful to the cell . If levels become too high, excess is removed through the plasma membrane.
2.NUCLEUS:The cell nucleus is like the brain of the cell . It helps to control eating , movement and reproduction.The nucleus is the largest organelle in the cell. It contains DNA of the cell.
3.MITOCHONDRIA:Harvest energy from organic compounds and transfer it to ATP. They generate the energy that the cell need, So they are also known as power house.
4.RIBOSOMES:Ribosomes are either free or attached to the rough ER and play a role in protein synthesis.Ribosome assembly begins in the nucleolus and is completed in the cytoplasm.Made of protein an RNA molecule.
5.ENDOPLASMIC RETICULUM:It’s a tube like passageways where proteins from the ribosomes are transported around the cell.Two types of Endoplasmic reticulum are their:
1.Rough Endoplasmic Reticulum: ribosomes attached to it , It makes proteins.
2.Smooth Endoplasmic Reticulum:No ribosomes attached to it So, it generally makes lipids.
6.GOLGI APPARATUS:The Golgi apparatus processes and packages proteins get address labels that direct them to other parts of the cell.
7.VESICLES:Vesicles including lysosomes(digestive enzyme) and peroxisomes (detoxification enzymes – liver and kidney)
8.CYTOSKELETON:Cytoskeleton is made of protein fibers that help cells move and maintain their shape.
