Most of the steel strapping manufacturing factories or whole sale dealers have a common problem in setting up a new factory of their own by selecting proper scale of production line, whether by big scale such like 30,000 tons/per year or small scale of workshop such like productivity of 5000 tons/per year.
The difference of investment between them is huge.
There are many multiple choices for the steel strapping manufacturing equipments.
A) 30,000 tons/per year production line with South Korean technology will be around 1.2 millions USD
B) 5000 tons/per year production line with Chinese 30 years working experience will be 0.1 million USD
C) 5000 tons/per year production line with cold rolling machines for hot rolled coils equipped with acid processing line will be 0.2 million, by which line you may roll different thickness of coil according to customer's request without waiting too long from Big Potato maker of hot rolled coils and make better quality for the coil before tempering.
We strongly suggest that in a realistic way of staring new production of the steel strapping a simple and easy equipment would be better choice among them.

Introduction to the steel strapping production line
(1) The formation of equipments:
The tempered steel strapping has been produced by adopting continuous production line in which the raw materials are processed with acid washing to remove the oxidation cover, and loaded into cold roll machine to rolled into required sizes and slit into width required for final product by slitter and winded into coils.
The coils are loaded into tempered tempering box and processed by heating oven continuously and turned out to the color of blue tempered and finally winded into coils by winders.
(2) The equipments needed for tempered steel strapping.
2-1: Acid washing.
This process consists of loading machine, acid washing tunnel, rinsing tunnel, and pulling machine.
Loading or pulling machine, power of motor is 3 KW, weight, 0.5 ton for loading raw material belt steel coil into acid washing tunnel.
Acid tunnel, used by materials either stone tunnel or Fiber Reinforced Plastics
2-2:Rolling machine, cold rolled machine.
(a) 4 rollers cold rolling machine, φ280x400
Main motor 45 KW speed adjustable
Roll down motor 2 kW 4 grades
Reducer motor LZQ 850
Rolling speed 35 meters/minute
The above machines are equipped with φ300x350 moment expanding winder:
main motor 25KW moment motor
reducer LZQ 350
weight one ton.
(b) 2 rollers cold rolling machine, φ165x350
Main motor37 KW 6 grades
Roll down motor 2 kW 4 grades
Reducer motor LZQ 750
Rolling speed 25 meters/minute
The above machines are equipped with φ300x350 moment expanding winder:
main motor 25KW moment motor
reducer LZQ 350
weight one ton.
(3):Slitter
The slitter has speed adjustable motor controlling speed for effective production. It consists of loading disk, precisely adjusting slitter, speed adjustable winder. It can slit the belt steel coil into 8mm—300mm, thickness, 0.1—1.5mm, the rolling blade diameter is 160mm. The main machine motor has power of 3 KW and winder power is 5.5 KW, the machine unit weights about one ton.
(4) Tempered related machines.
4-1: loading box, for loading slit coils, 16 coils/unit, weight, 0.6 ton.
4-2:rubber roller for loading before temper oven, weight 0.2 ton.
4-3: steel roller loading machine for loading after temper oven equipped with motor being used for adjusting speed of production according to tempering conditions.
Motor power 5.5KW
Machine weight 0.4 KW
4-4: temper oven this electric powered oven is special machine for heating processing.. Through processing of this oven, the surface of the strapping has good performance in physical chemistry, with firm and even layer of color without losing color, the user may adjust the tune of color according to their needs. This temper oven is used for normal steel strapping surface processing and make the surface of strapping with certain thickness of oxidation protection layer having a good effect in rust protectioin.
Oven power 100 KW
Weight 4 tons
Outside size 6000x1000x1300
(5) Tempered coil winder
The winder has a combination system with multiple units which form the winding system, the user may determine the quantity of the single units according to their planned scale of production. It is used by expanding friction step-less speed adjustment with stepping clutch structure, with features of advanced technology, easily operating and high efficiency.
Coil hole diameter 200mm 300mm 400mm(for painting)
Maximum out coil diameter 650mm
Power 5.5KW—7.5KW ( 1.5KW x 16 units = 24 KW for painting)
(6) controlling disk used for controlling oven and winder
(7) Painting oven this electric oven has used advanced technology in roasting and drying with combination of painting, roasting, fixing, waxing, drying being a systematic integrated special machine. Mainly used for roasting and drying of steel strapping surface painting, waxing, etc.
The oven is vertical type, height 18000 and 3000x3000 in ground space.
