Founded in 2004, with years of continuous efforts and development, we have become a morden enterprise of R&D, production in extruded aluminum production and fabrication. Our new factory with morden production line was builded in 2015, we have complete production lines, including anodizing, electrophoresis, powder coating, wood grain heat transfer printing, fluorocarbon powder coating, injection heat-insulation, strip heat-insulation. Products can be used in various architectural and industrial industries, like building and constructions, transportation, infrastructure, automotive, enery, and ect.
Adhere to the concept QUALITY FIRST, we produce strictly according to national and international standard. Only accept standard pure aluminium material, with scientific production management to ensure the stalibity of the production and quality.
At present, our customers throughout the country and exported to Africa, South America, Southeast Asia and other international markets. We commit to improve a better life in building construction, and a higher quality in engineering construction.

Q1: What are the advantages of using the 6000 series of alloys in aluminum extrusions?
A: The 6000 series, which incorporates magnesium and silicon, provide good extrudability,
strength, corrosion resistance, formability and machinability -- which explains why it’s also
JJT’s alloy of choice for all our aluminum extrusions.
Q2: If I wish to send an electronic drawing to you, what types of files can you accept?
A: We accept many file formats such as DXF, DWG and IGES.
Q3: Why do extrusion companies always ask me to sign off on a drawing before they can
order tooling if I’ve already provided a drawing?
A: Oftentimes, we find a few key dimensions that are missing from the original drawing
that need to be clearly identified. Other times, we have taken exception to a tolerance,
dimension, alloy, note, surface condition, etc. It’s just our way of documenting exactly
what we have agreed upon.
Q4: What is the difference between anodized and mill finished?
A: Mill is the raw state of aluminum as extruded - no surface treatment. Anodized (also
known as Satin Clear or Clear Anodized) is an electrolytic process. This process increases
corrosion resistance and weather resistance.
Q5: What About Anodizer Rack Marks?
A: Electrical contact must be made to each part to be anodized. The more electrical
current required, the greater the electrical contact. The size of the contact therefore
depends on the anodizing process and the size of the part being anodized.
