Contractors can create confusion when two products look similar, use similar materials and carry similar warranty language.

Gentek SteelTek® and SteelSide® are a good example.

Both are current Gentek steel siding systems.

Both use Galvalume® AZ-50 steel.

Both use PVC exterior finishes.

Both emphasize dimensional stability, smooth wall lines, woodgrain appearance and low maintenance.

Gentek currently positions SteelTek Steel Siding as a two-profile steel system with D4 Clapboard and 8" Clapboard.

Gentek currently positions SteelSide Steel Siding with three profiles: D4 Clapboard, D5 Clapboard and 8" Clapboard.

That profile difference becomes one of the clearest reasons a contractor might choose one product over the other.

Start With What SteelTek and SteelSide Have in Common

This is important because contractors should not exaggerate small differences to create a sale.

Review current SteelTek specifications and SteelSide specifications directly through Gentek before presenting either product.

The similarities are substantial. That is exactly why the profile difference matters.

The Biggest Current Difference: SteelSide Adds D5

That means the homeowner who wants a traditional 5" exposure has a natural reason to consider SteelSide.

"If you like the five-inch clapboard scale, SteelSide gives us that profile within Gentek's PVC-finished steel lineup."

That is a project-fit recommendation—not an arbitrary upsell.

SteelTek D4 vs. SteelSide D4

If the homeowner wants D4, the profile question alone may not separate the two products.

Both current D4 systems use:

• Two 4" exposures per panel
• A 1/2" butt projection
• Woodgrain texture
• PVC finish
• Galvalume AZ-50 steel construction

At that point, the contractor should stop manufacturing distinctions that the homeowner cannot see or benefit from.

Instead investigate:

"Since you like the D4 profile, let's compare the actual available colors, material availability and installed numbers instead of pretending these products are dramatically different where they aren't."

That is how product knowledge creates credibility.

SteelTek 8" vs. SteelSide 8"

The same logic applies to the 8" profile.

Gentek currently lists both systems with:

• 8" exposure per panel
• 1/2" butt
• 12'6" panel length
• PVC finish
• Woodgrain texture

If the homeowner wants the wide horizontal look, both deserve consideration.

"Both SteelTek and SteelSide give us this wide eight-inch horizontal profile. Now let's determine which product makes more sense based on the exact color, availability and project details."

A strong salesperson does not force a product distinction where the homeowner receives little meaningful difference.

When SteelSide Has a Clear Design Advantage

The answer is straightforward:

SteelSide's D5 uses:

• Two 5" exposures
• 1/2" butt projection
• 12' panel length
• PVC finish
• Woodgrain texture

Current specifications are listed on Gentek's SteelSide product detail page.

Why Might a Homeowner Prefer D5?

The difference between D4 and D5 is not simply one inch.

Exposure affects the visual rhythm of the entire exterior.

"Neither exposure is automatically better. The question is which proportion looks better on your house."

If D5 wins the design decision, SteelSide becomes a logical product recommendation.

Compare the Finish Correctly

Unlike SteelTek Supreme, this comparison is not primarily a PVC-versus-Kynar conversation.

Gentek currently identifies both SteelTek and SteelSide profiles with PVC finishes.

That means your salesperson should not say:

"SteelSide has the premium coating."

unless there is current manufacturer documentation establishing a specific coating difference for the products being quoted.

Better:

"Both of these systems currently use PVC-finished Galvalume steel, so profile selection and project fit become especially important."

Accurate selling keeps competitors from dismantling your presentation later.

The Current Color Palettes Are Also Very Similar

Gentek currently lists the same nine classic colors on its SteelTek and SteelSide product pages:

These colored boxes are for organization only and are not intended to represent Gentek's exact product colors.

Gentek recommends using actual product samples for final color selection because lighting, screen settings, viewing angle and profile orientation can affect appearance.

That guidance appears on the current SteelSide product page and should be part of any professional color-selection process.

If Colors Are the Same, Stop Selling the Color Count

This is where sales discipline matters.

If the homeowner wants Dover Gray and both systems provide the correct current Dover Gray option, the color may not help separate the products.

Move on.

Evaluate:

• Profile
• Availability
• Accessories
• Project specifications
• Material package
• Installed cost

Do not spend five minutes differentiating two things that are effectively the same for that homeowner.

Dimensional Stability Is a Shared Steel Advantage

Gentek emphasizes high dimensional stability for both SteelTek and SteelSide.

The rigid steel panels are designed to resist buckling and waviness associated with expansion and contraction during temperature changes.

Gentek also notes that the rigid siding can help subtly conceal certain imperfections in the exterior substructure and maintain smooth, straight wall lines.

Homeowner explanation:

"Whether we use SteelTek or SteelSide, one reason we're discussing steel is its rigidity and dimensional stability. Gentek emphasizes smooth, straight wall lines with both products."

That is a steel-category benefit, not a reason to artificially pit these two products against each other.

The 1/2" Butt Is Also Shared

Gentek lists a 1/2" butt height across the current SteelTek and SteelSide horizontal profiles.

Show that physically.

Turn the sample sideways and say:

"This profile depth gives the siding more dimension and creates a stronger shadow line across the wall."

Again, this is a shared strength of the product category.

Compare Warranty Headlines Carefully

Gentek currently markets both SteelTek and SteelSide with:

Contractors should still use the exact current warranty document applicable to the product being sold rather than assuming identical headline periods mean identical legal terms.

Gentek provides current product warranty resources through its Warranty Center.

Never make warranty distinctions from memory when the actual document is available.

SteelTek vs. SteelSide at a Glance

When Should a Contractor Lean Toward SteelTek?

A contractor could say:

"You like the D4 profile, the color is available in SteelTek and the construction gives you the steel characteristics we have been discussing. I don't see a reason to complicate the project unless another product gives you something you actually value."

That is a customer-first recommendation.

When Should a Contractor Lean Toward SteelSide?

"The biggest reason I'm showing you SteelSide is the D5 profile. You told me you prefer that broader clapboard scale, and SteelSide gives us that option."

Specific recommendations are stronger than vague claims about quality.

Local Availability Should Be Part of the Decision

Salespeople sometimes discuss products as though every profile and color is sitting in every distributor's warehouse.

Real projects require real material.

Before making a final product commitment, verify:

• Current profile availability
• Current color availability
• Accessory availability
• Lead times
• Minimum-order requirements if applicable
• Delivery timing

Suburban Wholesale & Supply can help contractors throughout the Quad Cities, Eastern Iowa and Western Illinois confirm current Gentek product options and build the complete material package before promising a homeowner a specific system.

A product that looks perfect in a brochure is not the right application if it cannot support the actual project schedule.

Never Substitute Without Explaining the Difference

Suppose a homeowner selected SteelSide D5.

You should not simply substitute SteelTek D4 because both are steel.

The exposure changes.

The appearance changes.

The homeowner's design decision changes.

Do Not Choose by Product Name

"SteelSide" may sound more residential.

"SteelTek" may sound more technical.

Neither name should determine the recommendation.

Why This Comparison Matters in the Sales Academy

This lesson teaches something larger than the difference between two Gentek product names.

Contractors should learn to stop thinking:

"Which product am I supposed to push?"

and start thinking:

"What does this project actually require?"

That means understanding:

• Architecture
• Profile exposure
• Color
• Finish
• Warranty
• Availability
• Accessories
• Installation
• Installed cost

Product knowledge should make the recommendation narrower and more precise—not louder.
