GAYLORD BOXES TXHOUSTON · SINCE 2009
Tool shed

Three calculators.
Zero sales calls.

Everything a decent supplier should have told you before quoting, built so you can work it out yourself and check our numbers against your own.

No email wallRuns in your browserPublished assumptions
What is here: the Grade Decoder specs a box from your load conditions, the Load Planner converts a quantity into trailers, and the Impact Calculator quantifies what your reuse loop actually avoids. All three run in your browser and none of them require an email address.

Whole boxes. A rough number is fine.

No phone number required from us — we quote in writing so you have the numbers on paper. We never sell or share your details.

Why we publish these

Because the alternative is quoting into a fog

Most of the bad orders we see — over-specified walls, wrong grade, freight that costs more than the boxes — come from buyers who were never given the reasoning. A buyer who understands the physics writes a better RFQ, and a better RFQ is cheaper for everybody.

These tools give away most of what a salesperson would normally hold back. We are comfortable with that, because our advantage is a yard full of graded stock in Houston, not an information gap.

Worked it out? Send us the spec.

Or send us the question. Either way it comes back in writing with a real stock count attached.
