Typically mild steel can withstand vibration better because it has a higher density than the more brittle cast iron but cast iron may be better at absorbing vibrations than mild steel, due to its lower density.
The density of steel varies depending on the alloy. (Steel itself is basically an alloy of iron and carbon.) Mild steel has a density of about 7.75 g/cc at room temperature and around 7.00g/cc in liquid state(Most studies reveal that the density of steel in liquid is about 90% than in solid state). The "world" of steel is a large one, and a variation will be encountered when investigating different alloys.

Gates are made from mild steel, because mild steel is relatively easy to change shape of, is rather cheap and quite strong.
Galvanization is just a surface treatment, and says nothing about the strength of the core material. You could have mild steel, one piece galvanized and one not, and they'd be equally strong.
A galvanized iron is similar to steel; it is material that composed of cold-rolled and hot-dip galvanized mild steel. It has 7850 kilograms per cubic meter density same as a steel.
To calculate the weight per meter of a 140x140x12.5 SHS (Square Hollow Section) mild steel, you would need to first calculate the cross-sectional area (A) of the SHS using the dimensions provided. Then, you can multiply the cross-sectional area by the density of mild steel (7,850 kg/m^3) to get the weight per meter.

Lead has a higher density than steel.
what is the weight od 25x25x3 mm mild steel angle per meter
The weight of a 40x5mm thick MS (mild steel) flat bar per meter can be calculated by multiplying the volume (area x length) by the density of mild steel. The area of the flat bar is 40mm x 5mm = 200mm². The volume per meter would be 200mm² x 1000mm = 200,000 mm³. The density of mild steel is around 7850 kg/m³, so the weight per meter would be 200,000 mm³ x 7850 kg/m³ = 1.57 kg/m.
What is the weight of 50x50x5 mm mild steel angle per metre length? Density mild steel is 7.85 g/cm3 Volume is 2x(4.5x0.5x100)+(0.5x0.5x100)=475 cm3 Weight is 7.85x475=3728.75 g (per metre).
The most common steel is mild steel, also called plain-carbon steel. It's density is approximately 7.85g/cm3. (Wikipedia)
Typically mild steel can withstand vibration better because it has a higher density than the more brittle cast iron but cast iron may be better at absorbing vibrations than mild steel, due to its lower density.
That would depend more on the material that the chequered plate is made from. For example, normal mild steel would be about 7650kg per cubic meter. i.e. a specific density of 7.65. I would think what you're looking for is the mass per square meter which is approximately 65.25kg/m2 for a steel plate.
The weight of mild steel can vary slightly depending on the exact composition, but as a general rule of thumb, the weight of a 2mm thick hot rolled commercial quality mild steel sheet is approximately 15.7 kilograms per square meter.
Per the attached related link, the density (hence weight) of stainless is slightly more than the mild carbon steel. Using about 8.03/7.84 ratio of density, for the same volume of material the stainless will weigh 2.4 % more.
