flush door single,double doors measurement

single flush door

sizes
2500 mm length
700 mm wide
35 mm thick
1 mm laminated both side

how to measurement in sqm and sqft

2500 mm length divide by 1000 = 2.500
700 mm wide divide by 1000 = .700
multiply 2.500x.700 = 1.75 sqm per piece

1.75x10.76 = 18.75 sqft single door measurement.

Double doors measurement

sizes .
2500 mm length
700 mm wide
35 mm thickness
1 mm laminated both side
14 mm rebated both side

how to measurement double doors with rebated

1) 2500 mm /1000 = 2.500 m
900 mm + 14 mm=914 mm / 1000 = .914 m

multiply 2.5x.914 =2.285x10.76=24.5866 sq ft is fist single leaf .

2) 2500 mm /1000=2.5 m
900 mm +14 mm =914 00 /1000 =.914 m

multiply 2.5x.914=2.285x10.76=24.5866 sq ft is second leaf

so hence both leaf are sq ft multiply

example 24.5866x2 = 49.1732 sq ft total double door measurement.

Wooden Fire Rated Door

Product Description

These doors are installed in buildings to segregate its different compartments effectively. By separating the different parts of a building, these doors delay the spread of fire and smoke. Depending upon the fire hazard associated with the building, these doors act as barriers to the passage of smoke and fire to varying degrees based on its location. These doors are easy to install and maintain CLASSIFICATION OF WOODEN DOOR

(AAC) AUTOCLAVED AERATED CONCRETE BLOCKS

1 THE AAC BLOCKS ARE MOSTLY USED AS THE PACKING MATERIAL OF HIGH RISE BUILDING.

AAC IS A LIGHTWEIGHT PRECAST FOAM CONCRETE BUILDING MATERIAL SUITABLE FOR PRODUCING CONCRETE MASONRY UNIT (CMU) LIKE BLOCKS.

COMPOSED OF QUARTZ SAND, CALCINED GYPSUM, LIME, CEMENT,WATER AND ALUMINUM POWDER,

AAC PRODUCTS ARE CURED UNDER HEAT AND PRESSURE IN AN AUTOCLAVE.

1 What is the ratio between sand and cement while joining AAC block ?

ANS= 1 CUM AAC BLOCKS CONSUMPTION 28 KG MORTAR

2 How to calculate the proportion of AAC block for different different sizes

ANS= 600X200X100 MM .6X.2X.1 =0.012 CUM= NOS 84 BLOCKS
600X200X150 MM .6X.2X.15 =0.018 CUM=NOS 55 BLOCKS

625X240X150 MM .625X.24X.15 =0.0225 CUM=NOS 44 BLOCKS
625X240X200 MM .625X.24X.2 =0.03 CUM =NOS 34 BLOCKS

RED BRICKS

RED BRICK IS BUILDING MATERIAL USED TO MAKE WALLS, PAVEMENTS AND OTHER ELEMENTS IN MASONRY CONSTRUCTION.

RECTANGULAR MAKES SOIL-BEARING SOIL END SOIL COOKED

AND THEN RED BRICKS ARE READY

CC BRICKS

Cement bricks can be used to build homes as well as garden structures such as retaining walls,

What are the types of cement concrete?

Concrete bricks are made of cement and fine aggregate, and are cast in moulds. Clay bricks are formed from wet clay. The clay is then extruded and cut with wire,

Or pressed into moulds before firing. Extruded clay bricks often have holes from

The top to bottom surfaces. The holes save material, lighten the brick and provide a

Better mechanical key for mortar. Moulded clay bricks often used to have a depression or 'frog' in the top face to provide a key, but this is not now common

TMT BAR COMPULSORY BASIC RATE DIFFERENCE OF RATHI INDUSTRIES

{TOPIC}

MARKET COMPULSORY RATE DIFFERENCE TO ALL TMT BAR INDUSTRIES

DIA 8 MM RATE DIFFERENCE @ 2300

DIA 10 MM RATE DIFFERENCE @ 1500

DIA 12 MM BASIC RATE TO BE ACTUAL

DIA 16 MM RATE DIFFERENCE @ 500

DIA 20 MM RATE DIFFERENCE @ 500

DIA 25 MM RATE DIFFERENCE @ 500

FOR EXAMPLE = 12 M M BASIC RATE IS 33500 PER METRIC TON

SO IN THIS BASIC RATE DECIDED TO DIA RATE,{ HOW }

EXAMPLE = WE HAVE RATE ONLY 12 MM TMT BAR ITS @ 33500 SO PLUS 2300

ITS WOULD BE 8 MM DIA RATE LIKE THIS 35800.00
DIA 10 MM @ 35000.00 PER METRIC TON
DIA 16 MM @ 34000.00 PER METRIC TON
DIA 20 MM @ 34000.00 PER METRIC TON

floor tiles sizes 600x600 mm

{topic}
flooring tiles size 600x600 mm thickness 9 mm per box 4 pieces,

how to calculate in squire feet,
how many squire feet per box.

lets start, 600x600 divide 1000

.6x.6 =0.36 per piece sqm

0.36x4=1.44 per box sqm

so we are going to convert in squire feet 1.44 x 10.76 = 15.4944 squire feet in box
