Forms
Straight boards, arches, pipe covers and machined shapes appear in the catalog.
Materials / Calcium silicate board
Calcium silicate board
FCS board families, historical grade tables, surface options and drawing requirements for a material inquiry.
Materials
Boards and shapes in the FCS family
The supplied catalog separates calcium silicate board into a 1000°C series, a 1100°C series described for fireproof and sound-insulation door applications, and high-density grades. These are historical catalog categories, not current certified performance claims.
Forms include straight and arch boards, pipe covers and CNC-machined shapes. The catalog describes the material as non-asbestos; current composition and supporting documents must be confirmed.
Materials
Compare the form and finishing
Choose a board family and finishing basis before comparing its reference values.
Surface options
The low-density page lists original dimple surfaces and sanded/cut options.
Separate density families
FCS-50, FCS-85C and FCS-85G have their own reference table.
Project-specific basis
Exact size, tolerance, finish and current material data belong in the inquiry.
Materials
Three distinct catalog groups
Keep the low-density, H-series and high-density tables separate. A grade name alone does not define an approved application.
- FCS-17 / 22 / 25 / 27
- The source’s 1000°C board group; different densities and strength values.
- FCS-25H / 27H / 30H
- The source’s 1100°C group; confirm the complete door or insulation assembly.
- FCS-50 / 85C / 85G
- High-density group with separate compression, shrinkage and conductivity data.
Materials
Use the source context carefully
The catalog names straight and arch insulation boards, pipe covers, machined shapes and door-related board applications. It does not provide a verified fire-rating or acoustic test package for a finished assembly.
Define the use position, adjoining layers, temperatures, loading and dimensional requirements before selecting a grade.
Materials
Historical FCS reference tables
The following values retain the supplied catalog’s units, inequality signs and test conditions. They are not a reconciled current purchase specification.
The FCS-50 shrinkage cell gives ≤1.5% with a 1000°C × 3 h condition; the FCS-85 columns use the surrounding 24 h row condition. No separate FCS-50 thickness value is supplied.
Historical typical data only. Request a current approved TDS and agree the test basis for the actual grade.

Materials
Confirm dimensions, finish and evidence
The source lists a dimple surface without four-side cutting as its default low-density finish and double-sanded/four-side-cut alternatives. The high-density page lists double sanding and four-side cutting. Any old surcharge wording is not a current price or supply commitment.
Pending confirmation
- Current grade-specific TDS and composition documents
- Drawing, dimensions, tolerances and finishing standard
- Applicable assembly tests, if fire or sound performance is required
Materials
Order-specific inspection documents
The historical product tables do not establish a current batch result, applicable certificate or approved installation. Agree the required material and dimensional inspection records for the actual order.
Pending confirmation
- Required batch report and test method
- Issuer, holder and validity of any certificate
- Authorized project evidence if a case is requested
Materials
Packing and supply for the board
Specify the board shape, quantity, surface protection and destination. No pieces-per-pallet, gross mass or container quantity is established by these calcium silicate pages.
Standard IFB pallet counts are not assigned to calcium silicate boards. Packing, handling, sample terms, trade conditions and lead time remain order-specific.
- Drawing / finish
- Identify cut edges, sanding and any machined features.
- Packing / quantity
- Confirm protection, unit count, pallet arrangement and mass.
- Destination / documents
- Define unloading needs, shipment documentation and responsibility.
Materials
Questions before an order
Are the catalog temperatures current application guarantees?
No. They are historical grade references; current material data and assembly conditions must be confirmed.
Are dimensions and CNC-machined shapes available as a standard schedule?
The source names those forms but does not supply an approved current drawing or tolerance schedule.
Can I apply IFB pallet counts to these boards?
No board loading quantity is established here. Agree a board-specific packing and weight plan.
