8. Processing Service
Henan Supioneer Metal Materials Co., Ltd. is not only a
professional steel plates supplier, but also specialize in steel
plate processing service, we mainly provide service in the
following three areas:
(1) Cutting
With advanced digital cutting equipment and advanced cutting
technology, we’re able to cut steel plate which thickness is up to
600mm. Our service aim at reducing the processing procedure
and production cost to save the expense for customers
eventually.
(2) Surface polishing
Descaling and defects removing are required to surface finish of
steel plates for special use. After been put into production in
recent years, our surface polishing equipment have provided
users with nearly ten thousand tons of steel plates use for
offshore oil platform, pressure vessel, and other fields.
Cutting Process
(3) Preprocessing
Doing a series operation from shot blasting cleaning
painting drying spray marks, to prevent steel plates from
rusting in a certain period of time.
Now we can process 12 main series about more than 300 steel
grades, the dimension of cutting piece is: thickness: 8~600mm,
width≤4.6mm, length ≤17m.
Steel plate cutting solution shows its unique superiority: product
linearity is good, high quality kerf and cutting surface is bright
and clean. Its tolerance of straightness is not more than 0.5mm
per meter, verticality is ≤3mm per 100mm
thickness, boundary dimension ≤1mm, cut finish of thickness ≤
100mm is up to ▽12.5, and up to ▽25 of thickness more than
100mm.
