Three factors of affecting the cost of steel structure plant

The steel structure workshop is destined to have a strong construction market share due to its beautiful appearance, short construction period, high degree of industrialization and resource reuse. The cost of steel structure workshop is also a concern of many people. It can be used to control the cost and the technical advantage of steel structure plant. It is the key research object of many steel structure enterprises.

steel structure plant

There are three main factors in the cost of steel structure plant:

A, raw material factors

Steel and sheet are the main components of the steel structure plant, accounting for about 70%-80% of the total cost of the steel structure. The fluctuation of the market price of steel structure raw materials directly affects the cost of the steel structure plant. The material of the section steel differs greatly from the price of the carrier surface and the thickness of the panel and the material. The raw material of steel structure is the main factor in the construction cost of the shadow steel structure plant.

B, design factors

Reasonable design is the fundamental problem of saving raw materials to control the cost of steel structure plants. Different design schemes of steel structure workshops are important reasons for the change of raw material quantity, which directly affects the total cost of steel structure workshops.

C, construction and installation factors

The length of the construction period is also part of the cost of the steel structure plant. The proficiency of the installation technology is the main reason for the length of the construction period. The construction of the structural plant is a systematic project involving a wide range of factors and many influencing factors. The construction period, policy changes, and large amount of engineering can all affect the cost of the steel structure plant.

Operating manual book for the double layer roll forming machine

Operating manual book for the double layer roll forming machine
Below picture is our new finished double layer roll forming machine
Here we share the operating manual book for the double layer roll forming machine, firstly please check below electrical drawing:
Wiring:
A machine power is three fire wires to one zero line, three were connected FireWire cable row A, B, C (1,2,3), zero line N (10) and connected to the solenoid valve common neutral, U, V, W (4 , 5,6) then press tile machine motor, U1, V1, W1 (7,8,9) connected to the pump motor, drop the knife solenoid valve control wire to K1 (11), l knife solenoid valve control wire to K2 (12) .
Simple operation:
Before transmission should automatically switch to the off position screwed (counterclockwise twist it).
 Press the button to start the pump. Note steering pump motor.
 Follow the onscreen instructions to select languages.
 Press and hold the tile machine forward, the board went to the outside edge, hold down the scissors cutting board, knife raised up by scissors upper limit.
 Screen display working status, the key clears the current number of copies; button clears the current length.
 screen display working status, length or button to select the number of copies.
 After all set to unscrew the automatic switch (clockwise twist it), the machine to work according to the set of data. After the work is completed, the machine stops automatically.

shutter-door-slat-roll-forming-machine-2
If you still need to continue to work the same length, just click the ALM key (key has cut the number of copies is cleared), the machine will be set according to the number on the screen and then work again.
If you need to change the length, automatic switch should stop. And then set the next production tasks. Also note onscreen has been cleared before the next start to cut the number of sheets automatically (ALM key press on the display).
 Automatic switch halfway down simply screwed back (counter-clockwise twist it), while continuing to work and then unscrew the automatic switch can be activated by pressing the pump.
* If the board does not match the length and requirements, according to adjust the screen, in the original amount of compensation based on the re-adjust the compensation amount plus or minus compensate. (Before correction plate length + compensation amount plus – minus compensation board after adjustment = length)
 Frequency machine deceleration distance, usually 200 mm, general machine this value is meaningless.

The reasons why some profiles are not suitable for the 2 in 1 double production roll forming machine

The reasons why some profiles are not suitable for the 2 in 1 double production roll forming machine
The drywall channel partition joist roll forming machine, As the machine C stud and U track channel roll forming machine are popular in 2016 year. For example, the 50 C channel and 50 U channel, the 75 C channel and the 75 U channel, the 100 C channel and 100 U channel profile machines. They can be designed as one separate machine, and double production 2 in 1 machines. The double production 2 in 1 machines are very popular in 2016.

2 in 1 double production roll forming machine
For the ceiling channel roll forming machine too, the double production 2 in 1 machines are popular too. For example, the 60×27 ,27×28 profile machine. It can be deigned as the separate machines, and can be designed as one machine with one shaft with 2 sets of molds and the double production machine lines.
Below are some pictures of the double production lines:
Today a customer inquiry a shutter door and the U guide roll forming machines, they want a U guide and the shutter door machine double production line 2 in 1 machine. After i checked with our engineer , we told him that the double production line are not suitable for U guide and the shutter door profiles. Not all the profiles and suitable for the 2 in 1 double production lines.
Below are the reason why Not all the profiles and suitable for the 2 in 1 double production lines.
(1)The 2 in 1 double production line is suitable for the profile which is with the thin thickness and with small quantity steps stations. So the double production lines are not so big, and convenient to load and unload into the container.
(2)The shutter door profile thickness is about 0.8 mm while the U guide profile thickness is about 2.0mm. So with different thickness, the two machines length are not same.

What profiles are suitable for the double production 2 in 1 machine lines?
For example, the 60×27 27×28 profile, the thickness is 0.3 mm of both profiles, and both separate machines are small, so it is nice to have the two small machines together to form a double production line to save the space.
The other side, the 60×27 27×28 profiles are near, and both separate machines are similar.
Below is the pictures for your reference:

2 in 1 double production roll forming machine1
After the explanation of the double production 2 in 1 machines, if you have understand the designing of the double production 2 in 1 machines. If you have any inquiry of some certain profiles, kindly send us the profiles drawing, we will design the machines for you, to check if it is suitable for the single production machine or the double production line 2 in 1 machines.

The advantages and disadvantages of different decoilers

We can produce different types of decoilers for you, we are professional manufacturer of the decoilers, we have produce the decoilers for more than 17 year. Our decoiler quality is very good and we can design and produce the decoiler for you as your personal requirements. So if you have the demand of the different decoilers you can let me know.

Normally the decoilers are used for the cold roll forming machines, some used for the roof tile roll forming machines and some used for the purlin roll forming machines and keel roll forming machines. The function of the decoiler is to support the steel coils and to feed the material to the forming machines.

There are manual decoilers and hydraulic decoilers, the hydraulic decoilers have more functions than the manual decoilers, the hydraulic decoiler is electric transmission and hydraulic expansion, and at the same time the price is higher. Normally the manual decoiler is enough for the production, because it is cheaper, this will save a lot of money for the buyer.

Normally the decoiler for the roof tile roll forming machine is 5 tons loading capacity and the purlin roll forming machine is 3 tons loading capacity, and for some keel roll forming machines, 1.5 ton loading capacity is enough. Our decoiler are customized, so if you want to buy one decoiler, you just let me know where you want to use this decoiler and the detail requirements of the decoiler you demand, then we will design and produce the decoiler for you.
