Specifications
Chalkboard and Chalkboard PLUSTM
General: All writing surfaces will consist of an Alliance
Ceramicsteel Chalkboard and Chalkboard PLUSTM panel, manufactured
by Alliance America, P.O. Box 920488, Norcross, GA 30092.
Materials: All Ceramicsteel panels will be supplied with a
28 gauge std. (24 gauge optional, subject to minimum order limitations)
steel face. The sheet will be properly pre-cleaned and treated. The ceramic
finish is fused to the steel sheet at a temperature of approximately
1200°F*.
Finishes: The ceramic finish will consist of a specially
formulated glass substance applied by machine. Base metal will be coiled
enameling steel of an alloy suitable for the application of architectural
porcelain employing a continuous coil process. Base metal will be properly
pre-cleaned and treated, to assure complete bond between the steel and the
subsequent ceramic coatings. Both surfaces of steel based metal will receive
a ground coat of ceramic frit to be fused to the metal in a firing operation
used exclusively for ground coat application to prevent contamination. A
color cover coat of ceramic frit will be applied to one surface of the
ground coat and fused by a firing operation used exclusively for color
application. All ceramic coatings will be machine applied with automatic
spray equipment to insure maximum finish uniformity. Firing temperature will
be approximately 1200°F*. Panels will be specified in any standard color
listed on this color guide. The gloss of writing surfaces will not increase
by more than three units when subjected to wearability tests specified in
testing procedures for 30 hours (approximately 126,000 Strokes).
Handling and Storage: Ceramicsteel panels must be stored on
edge in a dry location. Improper storage may lead to warping and
irregularities.
Limited Warranty: For the lifetime of the original
installation, the manufacturer warrants that the ceramic finish under normal
conditions of use shall not exhibit excessive fading or color, crazing,
cracking or flaking. The manufacturer's obligation under this warranty is
limited to supply without charge, new products for the defective goods, or
at it's option, Alliance America may refund the purchase price thereof with
due allowance made for the service rendered by such products. All products
are sold and warranted only pursuant to our published terms and conditions
of sale. Except as expressly provided in our published statement, we make no

Criteria
Writeability:
Accepts sharp, virtually
unbroken line. |
Chalkboard Fine tooth
matte finish produces solid chalk line with minimal dust. |
Chalkboard PLUSTM
Low-gloss finish gives full color value of
chalk and markers with negligible water wear. |
Visibility:
Provides good contrast with minimum glare. |
Low reflective
matte finish provides maximum chalk contrast with no glare. Chalk eraser
removes marks completely, retaining minimum residual chalk dust. |
Sharp clear
chalk and marker lines on low-gloss finish provide maximum contrast
with reduced glare and reflectivity. |
Erasability:
Erases easily without ghosts or excess residue. |
Wipes clean
with dry cloth or standard eraser |
Chalk wipes
clean with a standard dry eraser. A damp cloth is required to remove the
ink of dry erase markers. Other writing media can be cleaned with a
water dampened cloth while inadvertent strong ink, permanent marker or
crayon may require a mild soap or powdered abrasive. |
Washability:
Easily washed or cleaned without staining or surface damage. |
Easily washable
with water. |
Easily washable
with most mild soaps and detergents. Surface not affected by most strong
cleaners and basically non-staining due to non-porous surface. |
Magnetic Surface:
Holds standard wall magnets and teaching aids. |
Alliance
America Ceramicsteel surfaces are ideal for all magnets and magnetic
impregnated materials. |

America Ceramicsteel surfaces are ideal for all magnets and magnetic
impregnated materials. |
Wearability:
Must resist abrasion and impact. No loss or change of color. |
Vitrified
glass-hard ceramic surface fused to steel at temperatures of
approximately 1200°F. High resistance to impact damage, abrasion,
scratching and color fading. Alliance surface registers 6.5 on revised
Moh's scale. |
Vitrified
glass-hard ceramic surface fused to steel at temperatures in excess of
1300°F. High resistance to impact damage, abrasion, scratching and color
fading. Alliance surface registers 6.5 on revised Moh's scale. |
Fire
Safety:
Must not present a fire hazard. |
Alliance
America Ceramicsteel is 100% noncombustible, with class 1 finish rating.
0-0-0 fire hazard classification. |
