Electro-welded grating

High resistance to twisting, a consistent distribution of loads with the guarantee of a long life.

The electro-welded grating is made of bearing bars intersected with smooth round or squared twisted bars, electro-welded together in one only pressing process with a 2000 A electric discharge. The bearing bars have different sections from a minimum 20×2 mm to a maximum of 100×5 mm.

Bearing bars are the bearing elements of each panel which ensure them their load capacity. Cross bars have function to connect bearing bars by electro-welding, to ensure grating stability and at the same time, thanks to the equal distribution of the load, to increase their load capacity.

standard types of electro-welded grating

  • smooth round cross bar

Il grigliato elettrofuso con collegamento dei piatti portanti in tondo liscio assicura la stabilità del grigliato aumentandone allo stesso tempo la portata, garantendo elevate performance operative oltre a dare un elevato valore estetico.

  • twisted square bar

Il grigliato elettrofuso con collegamento dei piatti portanti in quadro ritorto è prevalentemente utilizzato nelle zone soggette a scivolamento assicura la stabilità del grigliato aumentandone allo stesso tempo la portata, garantendo elevate performance operative. Sono consigliate nelle zone industriali a rischio scivolamento

  • serrated

Il grigliato dentellato è ottenuto utilizzando piatti portanti  in laminato o in cesoiato superficialmente dotati di denti opportunamente sagomati, generalmente congiunti da collegamenti in quadro ritorto. Questa particolare combinazione è studiata per rispondere alle norme antinfortunistiche ove sia richiesta una particolare funzione antisdrucciolevole. Largamente consigliato ovunque si operi con liquidi o sostanze oleose.

  • ball proof

Grigliato per pavimentazione ad uso industriale realizzato con maglie non attraversabili da una sfera di 20 mm di diametro. Consigliato ove sia necessaria una protezione anticaduta.

  • heel proof

Il termine “antitacco” non ha alcun riferimento normativo, ma viene comunemente utilizzato per definire  un grigliato che abbia  le barre portanti di interasse uguale o inferiore a 15 mm.Viene normalmente utilizzato nel settore civile e dove vi sia una grande affluenza pedonale.

advantages

  • many application possibilities: from the housing industry to the offshore projects;
  • extremely resistant and inexpensive: it stands the most heavy loads in any laying-in-position condition;
  • versatile in case of different requirements: it allows for the production of panel of varied and special shapes.

unic panel

I pannelli standard di Grigliato Elettrofuso Baldassar hanno dimensioni di 6100 x 1000 mm.
I piatti portanti ( ) sono paralleli al lato più lungo, mentre gli elementi di collegamento a quello più corto.

I valori presenti nelle classi di portata sono garantiti solo ed esclusivamente se la direzione dei piani su cui appoggia il pannello di Grigliato Elettrofuso Baldassar è perpendicolare al senso dei piatti portanti, nel caso in cui fosse parallela alla direzione dei piatti portanti, la portata del pannello sarebbe fortemente compromessa.

shaping

Each building and every situation has different shapes and needs, because of this Baldassar has organized a technically specialized department, able to give special shapes and patterns to the product. Thanks to shaping, each grating element can have the most suitable contour for an easy inclusion and laying in position with minimum waste of material.

banding

Through the banding process, it is possible to give the grating panel a different finishing or a customized one according to the drawing of the client himself, like for example round or rounded, squared or shaped edges of stair treads. This deformation process is completely planned and performed inside Baldassar premises.

calandering

Thanks to a technologically advanced equipment, our technical department can apply any deformation on metallic profiles following detailed drawings, giving them a circular curve. The process is all within our production department therefore no need to wait for the performance from third party companies and no waste of time.

+ description

Electro-welded grating

High resistance to twisting, a consistent distribution of loads with the guarantee of a long life.

The electro-welded grating is made of bearing bars intersected with smooth round or squared twisted bars, electro-welded together in one only pressing process with a 2000 A electric discharge. The bearing bars have different sections from a minimum 20×2 mm to a maximum of 100×5 mm.

Bearing bars are the bearing elements of each panel which ensure them their load capacity. Cross bars have function to connect bearing bars by electro-welding, to ensure grating stability and at the same time, thanks to the equal distribution of the load, to increase their load capacity.

+ features

standard types of electro-welded grating

  • smooth round cross bar

Il grigliato elettrofuso con collegamento dei piatti portanti in tondo liscio assicura la stabilità del grigliato aumentandone allo stesso tempo la portata, garantendo elevate performance operative oltre a dare un elevato valore estetico.

  • twisted square bar

Il grigliato elettrofuso con collegamento dei piatti portanti in quadro ritorto è prevalentemente utilizzato nelle zone soggette a scivolamento assicura la stabilità del grigliato aumentandone allo stesso tempo la portata, garantendo elevate performance operative. Sono consigliate nelle zone industriali a rischio scivolamento

  • serrated

Il grigliato dentellato è ottenuto utilizzando piatti portanti  in laminato o in cesoiato superficialmente dotati di denti opportunamente sagomati, generalmente congiunti da collegamenti in quadro ritorto. Questa particolare combinazione è studiata per rispondere alle norme antinfortunistiche ove sia richiesta una particolare funzione antisdrucciolevole. Largamente consigliato ovunque si operi con liquidi o sostanze oleose.

  • ball proof

Grigliato per pavimentazione ad uso industriale realizzato con maglie non attraversabili da una sfera di 20 mm di diametro. Consigliato ove sia necessaria una protezione anticaduta.

  • heel proof

Il termine “antitacco” non ha alcun riferimento normativo, ma viene comunemente utilizzato per definire  un grigliato che abbia  le barre portanti di interasse uguale o inferiore a 15 mm.Viene normalmente utilizzato nel settore civile e dove vi sia una grande affluenza pedonale.

how to read a grating

C = distance between cross bars* P = distance between bearing bars*
H = bearing bar height
S = bearing bar thickness

*the distance is calculated CENTRE-TO-CENTRE between an elemnet an the other

advantages

  • many application possibilities: from the housing industry to the offshore projects;
  • extremely resistant and inexpensive: it stands the most heavy loads in any laying-in-position condition;
  • versatile in case of different requirements: it allows for the production of panel of varied and special shapes.

unic panel

I pannelli standard di Grigliato Elettrofuso Baldassar hanno dimensioni di 6100 x 1000 mm.
I piatti portanti ( ) sono paralleli al lato più lungo, mentre gli elementi di collegamento a quello più corto.

I valori presenti nelle classi di portata sono garantiti solo ed esclusivamente se la direzione dei piani su cui appoggia il pannello di Grigliato Elettrofuso Baldassar è perpendicolare al senso dei piatti portanti, nel caso in cui fosse parallela alla direzione dei piatti portanti, la portata del pannello sarebbe fortemente compromessa.

shaping

Each building and every situation has different shapes and needs, because of this Baldassar has organized a technically specialized department, able to give special shapes and patterns to the product. Thanks to shaping, each grating element can have the most suitable contour for an easy inclusion and laying in position with minimum waste of material.

banding

Through the banding process, it is possible to give the grating panel a different finishing or a customized one according to the drawing of the client himself, like for example round or rounded, squared or shaped edges of stair treads. This deformation process is completely planned and performed inside Baldassar premises.

calandering

Thanks to a technologically advanced equipment, our technical department can apply any deformation on metallic profiles following detailed drawings, giving them a circular curve. The process is all within our production department therefore no need to wait for the performance from third party companies and no waste of time.
