Force to deliver Concrete
We need 1 bar for pumping every 3 meter of horizontal concrete pipe, we need 1 bar for pumping every 1 meter of vertical concrete pipe.
Mild steel plate cutting charges
Q: To cut mild steel plate 8 1/2″ x 3″ with thickness 5/8″(5分）, price of steel is RM2.5 per pound
(Calculations are done in terms of inches and pound)
Below is the calculation of mild steel and its cutting charges using a basic calculator
5分 x 8.5 x 3 /144 x 5.15 x 2.5 m+
= Rm11.3999 –> price of steel plate
8.5 + 3 / 12 x 0.15 x 5分 cutting
= 0.7187 –> cutting charges
Total = RM12.1087
About carbon steel
Carbon steel plate we commonly use 760, also known as S45C, the price is usually double of mild steel.
For example, currently mild steel is selling RM4.44/kg (as at 24 Dec 2021), 760 is selling RM9/kg
About Stainless Steel
Stainless steel we commonly use 1B, also know as SS304, the price is currently four times (~3.88 times) of mild steel.
For example, today mild steel is selling at RM3.50 (as at 15 Dec 2022), 1B is selling at RM13.57/kg
3mm x 4′ x 8′ is RM950.00
Cylinder Flat Sheet
To develop the blank flat length for a cylinder rolled from sheet or plate:
Essentially, you should calculate the centreline arc:
(Outside diameter – Thickness) x 3.1416 = Length of plate required
If we need a final pipe OD440 with 4.0mm steel plate, then (440 – 4.0 ) x 3.1416 = 1369.7376

Metal Bending
To bend a L shape
if A is 300mm
B = 300mm
T = 3mm
L = 600mm – (2 x thickness)
= 600mm – 6mm
= 594mm
The 6mm is what we called a bend deduction.
It may varies depending on K factor, bending tools and inner radius, generally the result is close to thickness times two.
