Technical White Papers
Four Deep-Dive Engineering Papers
Each paper is built on peer-reviewed manufacturer data, ASTM/ISO test methods and field case evidence. Open any paper for the full analysis, tables and cited references.
FRP vs. Steel & Aluminum: Corrosion Engineering & Lifecycle Cost
A head-to-head analysis of how uniform, pitting, galvanic and stress-corrosion attack degrade steel and aluminum in process environments — and why a 25-year net-present-value model shows FRP reaching payback in year 5–8 and saving 30–50% over the asset life.
- Corrosion mechanisms vs. material response
- Material property & installed-cost comparison
- 25-year NPV lifecycle cost model
- Chemical plant & coastal case vignettes

FRP Grating Structural Load Design
How to treat grating as an orthotropic plate/beam, compute section properties, apply ZeAllgrate safety factors, and why deflection — not strength — usually governs the FRP section. Includes a fully worked 1.2 m-span walkway example.
- Load types & design values (pedestrian to industrial)
- Beam theory, I / Z section properties by thickness
- Deflection limits L/100 – L/200 & 4:1–5:1 FOS
- Worked calculation with formula blocks

Chemical Resistance Engineering for FRP Grating
A resin-selection methodology: how hydrolysis, oxidation and solvent swelling attack thermosets, the limits of ortho/iso/vinyl-ester/novolac/phenolic systems, and a 20-chemical × 5-resin compatibility matrix.
- Attack mechanisms & Arrhenius temperature effect
- Resin systems deep dive
- 20 × 5 compatibility matrix (A–D)
- Step-by-step selection & coupon validation

Offshore & Marine FRP Grating
Design, corrosion and compliance for saltwater service: why FRP is corrosion-immune, 75% lighter than steel and non-sparking in hazardous areas — plus IMO/SOLAS/E84/NORSOK compliance and connection detail guidance.
- Salt spray, UV, humidity & hazardous-area demands
- Marine-grade resin & C-veil specification
- IMO FTP Code, SOLAS, E84, NORSOK, ISO 14122
- Thermal expansion, slip & SS316 connection design

How ZeAllgrate Builds These Papers
We treat white papers as engineering documents, not marketing collateral.
Peer-Reviewed Data
Mechanical, thermal and chemical values are drawn from established manufacturer technical catalogs (leading industry suppliers of molded and pultruded FRP grating) and from consensus design guidance (ZeAllgrate Guidelines for the Engineer/Designer, ACMA), not estimated promotional figures.
Cited Standards
Every physical claim ties back to a named test method — ASTM D638 tensile, D790 flexural, D695 compressive, D792 density, D570 water absorption, E84 fire performance, D648 heat deflection, plus ISO 14122 and OSHA 29 CFR 1910.23.
Practical Engineering Focus
Numbers are presented as indicative ranges, safety factors are explicit, and each paper ends in recommendations a specifier can act on. Where a value depends on your exact resin and operating temperature, we say so and point to coupon validation.
Who Should Read These Papers
The white papers are written for engineers and specifiers building the design case: the Structural Load Design paper carries the load, deflection and section-property methodology; Chemical Resistance Engineering carries the resin-selection framework against a chemical list; Corrosion & Lifecycle Cost carries the economic comparison; and Offshore & Marine carries the class-rule and marine specification path. Each paper is built on the ASTM / ISO test basis and cites the standards behind its tables, so the numbers can be traced to the test method rather than taken on faith.
