CHEQUERED PLATE

Chequered plates are same as plates, However small projection of same steel as per picture will be there.The small projection is kept for skid resistance and it will be used for walk way platforms.

Generally chequered plates are designated as Cheqd.PL -A o/p X Length X Width

Example: Cheqd PL-6 o/p X 1150 X 750

The term o/p means "over plate" or "over plain". It means thickness of the plate is excluding the chequer

The weight of chequred plate is higher than plane plate considering the  projections (Chequers).

Total weight: length (m) x width (m) x thickness (mm) x 7.85 + extra weight = kg/plate

Generally the extra weight will be 6.1Kg approximately. However the following table shows the weight of chequerd plates











Please note that sectional properties of the chequered plate while designing for bending and deflection,are based on the plain thickness of the plate, excluding thickness of the chequer.

Have a nice day

UNIVERSAL COLUMN PROPERTIES

In continuation with my Previous post, Self would like to add the physical properties of Universal beams. It will be usefull for designers. It covers root radius, Depth of section and plastic modulus etc

UNIVERSAL COLUMNS

Dear Friends ,

Wish You a Happy New Year.

This is also same as Universal Beam. Equivalent to indian standard " H " section/ Wide flanged Beams. Based on design requirements it will be used. Universal column variable sizes are from 152 X 152 X 23 To 356 X 406 X 634

Universal Column Designates like UC-Size1 X Size2 X Size3

Here UC represnts Universal Column

Size 1 represents Height of the section
Size 2 represents Width of the section
Size 3 represents Unit weight per Meter

The table shows Details of  Universal Columns. 















Above Details are based BS 4: Part1: 2005
Properties of Universal Columns will follow next post
