Fiber Concrete Spacer with Tie Wire

Describe Fiber Concrete Spacer with Tie Wire

General introduction of HAN Fiber concrete spacer with tie wire

Fiber concrete spacer with tie wire is one of the product lines of HAN concrete spacers with a design that has attached tie wire to firmly tie the concrete support to the steel reinforcement, positioning the steel layer so that it does not shift when pouring concrete, creating an outer concrete layer to protect the reinforced concrete structure inside from environmental erosion such as: oxidation, steel layer corrosion causing destruction of concrete structures leading to unsafe construction.

Materials for manufacturing HAN's fiber concrete spacer with tie wire:

Fiber concrete spacer with tie wire are also produced from HAN concrete spacer materials including: sand, cement, stone, water, additives, reinforcing fibers, tie wire ... meeting current construction standards.

Tie wire embed can be:

Steel tie wire: Black annealed, Galvanized, Stainless Steel
Plastic tie wire: Pvc coated.

Technology for manufacturing HAN's fiber concrete spacer with tie wire:

HAN's fiber concrete spacers with tie wire is produced by concrete casting technology. Fiber concrete products are cast from molds for precise dimensions and low tolerances.

How to choose and use HAN fiber concrete spacer with tie wire to achieve high economic and technical efficiency.

No	Content	Should	should not
1	Design	You should choose the appropriate concrete spacer design based on specific needs. For example: flat base type is used for foundations, concave base type is used for floors, U-shaped type is suitable for upper floor steel, etc.	Don't choose just one design for all your different needs.
2	Size	You should choose to use single concrete spacer with size from 20mm - 150mm.	Consider choosing concrete spacer larger than 150mm if there are no special requirements.
3	Breaking Load	Should clearly understand the required calculated load and choose a concrete spacer with tie wire with the appropriate load-bearing capacity.	Do not choose a concrete spacers with tie wire with a load capacity lower than required
4	Usage rate	Should use more than the standard rating recommended by HAN	Do not reduce the quantity used even in the case of concrete spacers with tie wire with good load-bearing capacity.
5	Economic and technical efficiency	Technical and economic efficiency should be the deciding criterion when choosing concrete spacers with tie wire.	Do not base your purchase decision solely on the price of a concrete spacers being cheaper or more expensive than other types.
6	Packaging and storage	For frequent use, choose packaged, large quantity, convenient to store.	Consider storage conditions when choosing single size concrete block in carton box If the storage conditions outside the construction site are not suitable
7	HAN brand awareness	Should contact the official dealer or buy directly from HAN with packaging clearly stating HAN information (Product code, address, phone number).	Do not buy products that do not have the HAN brand clearly printed on the packaging.
8	Implementing personnel	Should have knowledgeable and experienced personnel work directly with HAN's technical consulting team when making purchasing decisions	Do not let the accounting department or purchasing staff make purchasing decisions without clearly understanding the technical requirements.
9	Key Points	For horizontal directions, the wire-tied feature will promote fast construction efficiency For positions that are likely to be displaced, the wire-tied feature helps to secure the steel layer. For projects that require fast construction, the wire-tied concrete spacer helps save construction time

Method of transportation and preservation of HAN's Fiber concrete spacer with tie wire:

Notes transporting

Do not drag the packaging on the ground, avoid throwing it from above if packing
When transporting concrete spacer bags or concrete spacer boxes, use a flat-floor truck.
Large bags, suitable products are placed below, the steel floor blocks on top (note code product: CSS050U, CSS070U, CSS090U, CSS110U, ...) are placed on top, do not stack too high.

Notes storing:

Should be kept on a cool, dry floor, avoid direct contact with soil, mud.
If packaged in bags, it can be left outside for 1-3 months.
If packaged in boxes, it must be placed on a pallet, not exposed to water or high humidity.

Factors to consider when choosing to use Fiber concrete spacer :

Customers should consider the following factors when choosing to use HAN concrete bearings, including:

It is necessary to rely on the current construction standards of Vietnam or foreign countries. And most importantly, the specified standard is being applied to the project.
The choice of concrete spacer depends on the nature of the structure and the type of concrete bearings used based on HAN's technical data sheet
The protective concrete cover required by the standard (eg EN206 paragraph 6.3 or other appropriate standard) specifies the nominal protective concrete layer.
The load of the pad from the weight of the reinforcement and additional loads such as foot traffic during concrete pouring, fixing and erection work.
Diameter and location of reinforcement - wall/slab - Horizontal or vertical
Reinforcement type - single bar or plate or mesh rebar
Single size type, simple, fast and cost-effective fixing
Multi-size fixed type - no tie or with pre-tied
Single size type with embedded tie wire, multi-purpose, secure fixing
Round type, Bar type, specialized design type....
External influences affecting concrete, such as pressure, temperature, chemical attack, moisture penetration, fire and corrosion
Concrete surface finishing - plastering work
Exposed concrete - traces of spacers become clear on the concrete surface
