JIS G3302 GB/T251B Gl/Gi Slitting Steel Strips Coils Gl
Coils Aluzinc Galvalume Steel Coils 0.35mm*168mm
Using master coils with accurate steel slitting produces narrow
customer-specific widths and winds the cuts back up onto a
recoiled. We safely join the Slit coil and then take it out for
additional packaging.
The course of steel cutting requires machinery with enough mass to
precisely cut the steel with uniform edges without burr. Each steel
slitting machine has a rated capability to cut only so many cuts at
a time. It is important that the steel slitter does not operate at
its maximum rated capacity. This will burden the machine and
produce a poor item. A steel slitter that needs more force and mass
to cut thicker metals will create poor edges. SRMM has heavy gauge
steel slitting machines that ensure an accurate and clean edge for
customer processing.
Precision coil steel slitting is a process by which wide coils of steel are fed through a slitter and cut into narrow strips of material. Each of these cut strips is known as a strand, and is then recoiled to create width narrow slit coil.
Our range of slitting capabilities puts our customers at ease, as they know that we have the right equipment to quickly process their orders. Our customers appreciate our high level of precision in the slitting process, as it spares them from having to deal with excess material waste in their own manufacturing process.
With our industry experience, cutting-edge rotary slitting knives, high-level skill operators and warehouse logistics, we are able to offer high-quality coil slitting services with the highest standard, efficiency and accuracy.
Based on customer demand, we supply long production runs but we also have the equipment and human resource to remain flexible and offer a rapid service even on small quantity requests.
We are able to produce strips in both aluminium and stainless steel and we have the capacity to run small, single runs to larger multiple coil operations.
After slitting the coil, our team will recoil the finished material and band the narrow coils. We aim to deliver all materials in pristine condition and our team is very meticulous with how all delicate materials should be handled.
In addition to slitting and blanking, we also have in house polishing facilities as well as being able to offer traverse wound coils.
Product Details:
1. Brief introduction
It is galvanized steel sheet with zinc and aluminum, and is the
ideal combination of anti-corrosion and alkali-resistance of zinc,
and the durability, heat-resistance, and acid-resistance of
aluminum.The galvanized layer
is consisted of 55% of aluminum and 43.3% of zinc and 1.6% of
silicon per weight

3. Application
1) Construction: Roofing, cladding, structural sections, composite
panels
2) Electric appliance: Washing machine, refrigerators, toaster,
microwave
3) Miscellaneous: Air duct, lighting, computer casing
4. Features
1) Formable, weldable and paintable
2) Superior long term corrosion resistance in the most atmospheric
conditions. This is achieved
through the combination of the sacrificial protection of the zinc
and barrier protection of aluminum
3) Hot dip galvalume coating out-perform galvanized coating from
2-6 times than galvanized steel
5. Packing details
Each hot dip galvalumetube wrapped by plastic film and waterproof
paper, one steel strip strapping
on the galvalume steel coil circumference. 3 - 5 coils tube packed
eye vertical on wood pallet, and
strongly strapped by edge protection, and at least 4 steel straps
through coil eye. Coil tube packed
eye to sky on wood pallet
