Properties of SAS products

Laboratory testing:
SAS is equipped with its own control laboratory wich tests the quality of raw materials and finished products.

Concrete components:
SAS uses only crushed marble or quarry aggregates and white and grey high-resistant Portland cement type 42,5 R.

Measurement tolerance:
±1mm in thickness, collection boxes and planters (±5mm in height).gardening

Weight tolerance:
±5% of the catalogue weight, tested with a totally dry product.

Colorants:
Metal oxides.

SAS products are made using 3 large groups of concrete:
White concrete / Grey concrete / Washed concrete

Density:
White concrete: 2.100 / 2.225 kg/m3  Grey concrete: 2.125 / 2.250 kg/m3
Washed concrete: 2.100 / 2.250 kg/m3

Resistance to compression:
White concrete: 400 kp/cm2  Grey concrete: 454 kp/cm2  Washed concrete: 265 kp/cm2

Water absorption:
White concrete: 4.2% of weight  Grey concrete: 4.8% of weight  Washed concrete: 4.3% of weight

Freeze-resistant:
Our products are all tested according to the German DIN 52 104-Z standard (the most stringent one), as follows:
No visible effect of chipping, fissures, cracks, etc. was observed after fifty freeze-thaw cycles. Freezing cycles: the temperature in the chamber is allowed to drop to -15º C in 4 hours and is maintained there for a further 2 hours. The product is then steeped in water at temperature of 15º C. These tests were carried out by our laboratory and endorsed by the officially-approved "MATERIAL-PRÜFUNGSAMT NORDRHEINWESTFALEN". Laboratory of Dortmund. SAS products have been tested by the University of Sheerbrooke in Quebec (Canada) according to the ASTMC-666/A norm as follows: after 300 cycles of freezing–de-frosting, (-50º C), the (V/Vo)2 average is 96 % while this norm settles a minimum of 60 %.

Static resistance:
Our Balusters (Serie-650 together with the Rail RBR-50 and the Classic Pier PBR-770) fulfil the ETB static resistance regulations Fassung June 1985: 3.1 (lateral static resistance), 3.2.2 (light blow) and 3.2.3 (strong blow). This has been certified by the German laboratory MPA in Dortmund.

Durability:
If SAS products are fitted and positioned correctly, used for the purpose for which they were designed and correctly maintained, they will prove highly durable.
These tests were carried out at our laboratory and checked by the Generalitat de Catalunya (Catalan Governement) approved laboratory PAYMA, S.A. in MONTCADA (Barcelona).

INFORMATION OF INTEREST

  • Our products are manufactured with marble aggregates and as a result slight differences in colour tones are inevitable.
  • Our products are supplied on wooden pallets, covered with shrink-wrap and in some cases strapped. The materials used in our packaging can be recycled.
  • We recommend you avoid stacking the pallets of our products, even though this is possible with certain models.
  • Products supplied in cardboard boxes should be stored in a dry area.
  • We have a graphic library of our products for AutoCAD. If you are interested in it, please download it freely from our website.
  • We can also offer a video on the installation of some of our products. If you are interested, please let us know.
  • The high cement content of our products may give rise to surface microfissures that do not affect the physical characteristics or the quality of the finish of the pieces.
  • The effect of humidity may cause the so-called "efflorescence" phenomenon in certain colour products. This is merely a whitish crystalline deposit on the product's surface which is beyond our control. It is characteristic of all quality products made with cement and will disappear with time and use.
  • No claims will be accepted 8 days after delivery of the goods. The responsibility of SAS is limited to exchanging or crediting defective products.
  • SAS reserves the right to alter the characteristics of its products without prior notice.
  • Most of SAS products have been identified with the “SAS” brand name.
  • We declive any responsability if our products have not been installed properly. For further information on manipulation and installation, please consult our web site.
