Gentek currently offers both SteelTek Supreme® Steel Siding and SteelTek® Steel Siding.

That creates an important contractor question:

"If both products are steel, why would I recommend one instead of the other?"

The wrong answer is:

"SteelTek Supreme is better because it costs more."

Contractors need a more useful answer.

Both products use heavy-duty Galvalume® AZ-50 steel and are positioned by Gentek around strength, dimensional stability, smooth wall lines and low-maintenance exterior performance.

The biggest differences are in the exterior finish, profile selection, texture, color palette and design flexibility.

Those differences create two legitimate steel positions instead of one good product and one bad product. :contentReference[oaicite:0]{index=0}

Start With the Biggest Difference: Kynar PVDF vs. PVC

This is the first distinction a contractor should understand.

Gentek specifically states that SteelTek Supreme's Kynar PVDF coating contains a performance additive that improves scuff resistance compared with PVC finishes. :contentReference[oaicite:1]{index=1}

At the kitchen table, keep it simple:

"Both products use steel. One of the biggest upgrades in SteelTek Supreme is the exterior coating system. Standard SteelTek uses a heat-fused PVC finish, while Supreme moves into Gentek's Kynar PVDF coating technology."

That immediately establishes a legitimate product difference.

The Second Major Difference: Four Profiles vs. Two

SteelTek Supreme gives the contractor considerably more design flexibility.

Gentek's current SteelTek Supreme lineup includes four profiles, while SteelTek currently offers two. :contentReference[oaicite:2]{index=2}

That difference can matter more than the finish for certain homeowners.

If the homeowner wants D5 or vertical Board & Batten, the decision may already point toward SteelTek Supreme.

Do Not Underestimate Board & Batten

Board & Batten is one of the clearest reasons SteelTek Supreme may deserve the upgrade.

The current SteelTek lineup does not include Gentek's 12" vertical Board & Batten profile.

SteelTek Supreme does.

"If Board & Batten is important to the exterior design, that moves us toward SteelTek Supreme because Supreme gives us that vertical profile within the same product family."

That is a design-driven recommendation—not an upsell for the sake of upselling.

SteelTek Supreme Also Offers a Broader Color Palette

Gentek currently lists twelve SteelTek Supreme colors and nine SteelTek colors. :contentReference[oaicite:3]{index=3}

This does not mean the Supreme palette is automatically better.

The homeowner may actually prefer a SteelTek color.

Always let the house and design drive the decision.

Texture Is Different Too

SteelTek currently uses a woodgrain texture on both of its profiles.

SteelTek Supreme uses roughsawn textures on D4, D5 and 8" horizontal profiles and a medium woodgrain texture on its Board & Batten panel. :contentReference[oaicite:4]{index=4}

This is exactly why contractors should keep physical samples of both products.

"Instead of me telling you which texture looks better, let's put them beside each other and see which one you prefer."

What Do the Two Products Have in Common?

Do not exaggerate the differences.

Both products are legitimate Gentek steel siding systems.

Gentek's current SteelTek page lists lifetime limited coverage, 50-year hail protection and 35-year chalk and color-change protection, matching the current headline protection periods shown for SteelTek Supreme. :contentReference[oaicite:5]{index=5}

Important: Use Current Warranty Documents

Contractors may have older SteelTek brochures in their files.

An older 2021 Gentek SteelTek brochure listed 15-year chalk and color-change protection, while Gentek's current 2026 SteelTek product page now states 35-year chalk and color-change protection. :contentReference[oaicite:6]{index=6}

This is exactly the type of detail that separates serious product training from memorized sales talk.

SteelTek Supreme vs. SteelTek at a Glance

When Should a Contractor Recommend SteelTek?

SteelTek can make excellent sense when the homeowner wants steel but does not need every Supreme upgrade.

A salesperson might say:

"Based on what you've selected, I don't think you necessarily need to move into Supreme. SteelTek gives you the steel construction and the profile you like, so let's price both and see whether the Supreme upgrades matter enough to you."

That builds enormous credibility.

When Should a Contractor Recommend SteelTek Supreme?

"The reason I'm recommending Supreme here isn't simply because it's our premium line. You specifically liked this profile, this color and the Kynar finish. Those are actual differences you would be buying."

That is how a premium recommendation should sound.

Use the Finish as the First Good-Better Comparison

Put the two physical panels side by side.

Ask:

"Before I tell you which one costs more, what differences do you notice in the surfaces?"

Then explain:

That is a legitimate good-better steel presentation because both options remain good products.

Then Compare Design Flexibility

Ask:

"Do either D5 or Board & Batten matter to your design?"

If no:

SteelTek may remain very competitive.

If yes:

Supreme has an obvious design advantage because those profiles are currently part of the Supreme lineup. :contentReference[oaicite:7]{index=7}

Compare the Actual Colors on the House

Do not assume twelve colors automatically beats nine.

The homeowner needs one color—not twelve.

Take actual SteelTek and SteelTek Supreme samples outside.

Compare them with:

• Roofing
• Brick
• Stone
• Window frames
• Garage doors
• Entry doors
• Existing permanent trim

"We're not choosing the product with the longest color list. We're choosing the product that gives this house the right color."

That keeps the sales presentation grounded.

How Should a Contractor Present Price?

Once the homeowner understands both systems, isolate the actual upgrade.

"Both options give you Gentek steel siding. The additional $_____ moves you into the Kynar PVDF finish and the Supreme profile and color package we've been discussing. Are those differences worth the additional investment to you?"

That is the real decision.

Do Not Make Supreme the Automatic Answer

This is the central training point.

If the homeowner wants:

• D4 siding
• A SteelTek color
• A woodgrain texture
• Steel construction
• A lower project investment

and does not place additional value on Kynar or the Supreme design options, SteelTek may be the smarter recommendation.

There is nothing wrong with saying:

"I can sell you Supreme, but based on what you've selected, I don't think you need to spend the extra money."

That sentence earns trust.

Likewise, Do Not Reduce Supreme to “Fancy SteelTek”

SteelTek Supreme has real differences.

If a homeowner values those differences, explain them confidently.

"Supreme isn't simply another SteelTek color. The coating technology changes, the available profiles expand, the textures change and the design palette becomes broader."

Make the premium tangible.

What Should a Salesperson Never Say?

Contractors Should Stock Samples of Both

This comparison is difficult to make from brochures alone.

A proper contractor sales kit should include:

Put both systems into the homeowner's hands and let the physical products help support the recommendation.
