Foundation Design Specification

1.To clear the site and

leveling.

2. Prepare the access

road.3.Excaveted and

casting the footing.

4.Casting stump and

cover up the footing.5.Casting the ground

slab.

6.Foundation work complete

Materials: Ultra Galvanized High Tensile Steel.

Triple layers coating system (Zinc, conversion film & resin)

20%-30% higher in yield strength

20% lighter in weight

Galvanized Steel Truss


All welded trusses will final applied with a zinc spray coating at every welding

point as a protection layer and to prevent rusty.

Used thicker thickness square tube’s webs with 1.6mm to 3.0mm with minimum

yield strength 350 Mpa compare to competitors which used thinner tube.

Hot dip Galvanized Tubing with Zinc coat mass: 600 ~ 800 g/m².

An effective venting system provides year round benefits:

During warmer months, ventilation helps keep attics cool.

During colder months, ventilation reduces moisture to keep attics dry. It also

helps prevent ice dams.

Other benefits: (all four seasons of the year)-added comfort-protect against

damage to materials and structure-help reduce energy consumption.

Attic Ventilation

Unvented:

Radiant heat penetrating through roof sheathing and attic

enters living areas of poultry shed.

Vented:

With proper ventilation, the heat is vented out of the attic,

keeping living areas cooler.


Double Storey Construction Methods

Steel Floor Deck Precast Concrete Slab

Solution to land shortage problem

Save concrete as much as 30%

Savings in form/mould materials

OR


A new way of building combined lying of the steel floor deck and reinforcing and

has remarkable saving in materials, work and expenses.

When lying the steel floor deck only a sparse support from below is needed. The

distance between the supports varies form 1.0m to 2.0m depending on the

thickness of the sheet and the concrete layer.

The completed slab (steel floor deck & concrete mixed) acts as a reinforced

concrete.

The steel floor deck is available in thickness between 0.8mm and 1.0mm with

zinc coated at both sides.

Able to fit the load of 250kg/m

Steel Floor Deck

2


Composite steel deck floors consist of

a profiled steel deck with a concrete

topping. Included in the concrete is

some light welded mesh

reinforcement which acts to control

cracking, to resist longitudinal shear

(A kind of force) and, in the case of

fire, to act as tensile reinforcement.

The profiled deck allow the concrete

and steel to bond and share load.

Composite action between the

supporting beams and the concrete is

created by welding shear studs

through the deck.

Steel Floor Deck Construction Details


I-beam size & thickness is depends on the structure & floor loading

design.

Steel Floor Deck - Floor Beam


No Description Benefits

1 Saving in structure materials Only separate beams and the edges of the slabs are bonded.

This save timber 70% - 80%

2 Easy construction of the structure The floor decks are easy assemble

3Saving in underside reinforcement

steel

No underside reinforcement needed. Save reinforcement steel

80% - 90%

4Thinner slabs can be used because

of the rigidity of metal sheet Save concrete 15 – 30%

5 Inexpensive cost the cost same as ordinary profiled steel sheet

6 Save time and money No discharging of the steel sheets

Since precast is manufactured in a controlled casting environment it is easier to

control the mix, placement, and curing.

Quality can be controlled and monitored much more easily.

Can cast regardless of any weather conditions and get the same results.

Less labor is required and that labor can be less skilled.

Rapid construction lead time on site.

Save topping concrete cost, the 50mm thickness is sufficient to support the

weight.
