FRP GRATINGS
Densons FRP Gratings are fabricated
by using Pultrusion FRP I-Sections of 30/8 mm &
25/8 mm as a load bearing sections and Pultrusion FRP
Rod 8/10 mm dia as load distributing/transferring member.
Both I-Sections and rods are manufactured by using continuous
Fiber and various type of polyester resin. The choice
of resin viz. Isopthalic, Bisphenol or Vinyl Ester depends
on the chemical and duty conditions.
It is suitable to be widely used in
such fields as petro-chemical, OECL engg., Shipplings'.
Water and base water treatment, paper making, wine making,
pharmacy etc.
It is also used as working tables, stair tread, ditch
cover, bridge side-walk, filter board, filling support
etc. It is an ideal loading element on corrosion circumstances. |

| Technical Data |
| Functions |
Characteristic |
| The FRP Grating
is suitable to be used in corrosive situations
such as acid, alkali etc. |
| |
Under
equal application situation, it's weight is
only 1/3 to 1/5 of steel, but it's strength
reaches the strength of normal steel. The material
function is different from plastic material
(no obvious brittle failure. It's deform is
changed along with the change of stress but
no scaling relations between them. It fully
absorbs impact force while keeping it's shape
because of its comparative smaller elasticity
modulus. FRP Gratings are made of high quality
fiber glass and resins. The product could transfer
heat to release if added ultra-violet resistance
material-having stronger aging-resistance function
Have better anti-skid function and could prevent
injuries from fall.
-
Being high insulation its
dielectric strength is 100kv per inch, therefore,
it could keep safe while walking on the
FRP Grating.
-
Non-electric spark. Therefore,
it could be used in such circumstances as
mine combustion gas etc. For avoiding the
accident caused by spark.
-
Non-Magnetism. The product
could take the iron or steel grating and
be used in the magnetism-sensitive circumstances.
FRP Grating initially will
be more costly than iron/steel but, in the longer
run due to its non-maintenance and longer service
life will be more economical and durable. |

Mechanical Behavior
A deflection arrow equaling 1:150 of the span is considered
standard in practice. The following table lists the
maximum admissible loads for reaching this arrow as
a function of the span. |
